Jul 16, · What is the rainforest? Tropical rainforests are forests with tall trees, warm climates, and lots of rain. In some rainforests it rains more than one inch nearly every day of the year! Rainforests are found in Africa, Asia, Australia, and Central and South America. The largest rainforest in the world is the Amazon rainforest in South America. Rainforests are lush, warm, wet habitats. Trees in the rainforest grow very tall because they have to compete with other plants for sunlight. Kapok trees, which are found in tropical rainforests.
Thick forests found in wet areas of the world are called rainforests. Most people are familiar with hot, tropical rainforests filled with trees that stay green year-round. But there are how to make a dress pattern from scratch kinds of rainforests, too. Temperate rainforests grow in cooler parts of the world, such as the northwestern United States and southern Australia.
Monsoon how to make a compost pit have a dry season and trees that shed their leaves each year. They grow in Southeast Asia. Montane rainforests, or cloud forests, grow in mountainous regions. The rest of this article will focus on tropical rainforests because they are important to the health of the entire planet.
Tropical rainforests occur around the equator in the hot, wet region called the tropics. They are found in parts of the tropics that arinforest more than 70 inches centimeters of rain each year. Tropical rainforests can be divided into several sections. At the top raonforest the forest is a thick layer called the canopy. It is formed by the spreading branches and thick leaves of tall trees. The canopy blocks much of the sunlight from the area below.
The canopy can be between and feet 30 and 50 meters above the ground. A few very w trees stick up above the rest of the how to get started free running. They are called emergent trees.
Many animals and insects live among the treetops of the canopy. The section below the canopy is called the understory. It contains small trees, shrubs, and plants. Many of these are saplings young trees. Their stems reach up toward the light. However, these smaller trees generally do not receive enough sunlight to grow into adult trees. On the forest floor, it is usually dark because the canopy blocks so much of the sunlight.
For this reason, only plants that can tolerate shade grow there. So little sunlight reaches the ground that the forest floor may be only lightly covered by ground vegetation. There may be open spaces between the tree trunks. If one of the trees that creates the canopy dies or falls, however, a gap may open in the canopy, allowing sunlight to reach farther down into the forest.
In such cases the ground vegetation may become thick and dense. The constant rain washes away many of the nutrients in the soil. To make up for that loss, bacteria, fungi, and insects on the forest floor help to break down dead plants and animals.
This process creates a thin, rich top layer of soil that provides nutrients to the roots of the plants and trees. Because this layer of soil is thin, most of the trees have shallow root systems. Tropical rainforests are known for the diversity of their plants and animals. Scientists believe that many of these species have not yet been discovered. The trees found in tropical rainforests stay green all year, though they do shed their leaves sometimes.
Palms are among the most common trees. Below the thick canopy, other plants have to compete with each other to get enough light. As a result, many plants use other plants to reach toward the sunlight.
For example, woody plants called lianas attach to the stems of other plants and climb from the ground to the canopy. Epiphytes, or air plants, are also abundant in the rainforest. These plants are not attached to the ground. They live on other plants and get water and minerals from rain and also from debris that collects on the supporting plants. Mosseshow to measure your fat percentageand orchids can often be found attached to larger plants.
Each area of the rainforest has thousands of species, or types, of animals. Many plant-eating animals live in the canopy—for example, monkeysflying squirrels, and sharp-clawed woodpeckers. At the lower levels of the forest are animals that run, flutter, hop, and climb in the undergrowth. On the rainforest floor are such animals as chimpanzeesgorillaselephantspigsdeerand leopards.
Many animals in the rainforest have rainfkrest characteristics. For example, sloths hang upside down, resting for hours at rainforesh time. The bright colors of the tiny poison dart frog warn other animals that it is poisonous and should not be eaten. Other id animals throughout the forests include antsbeetles how to open ips file, snakesand bats.
There are also many brightly colored birds such as toucans rainfroest, parrotsand macaws. A tropical rainforest is a delicate network of relationships between plants and animals.
Many plants, for instance, rely on animals to spread their pollen from flower to flower. At the same time, animals may depend on plants for their food and shelter. In addition, millions of people raibforest in the forests. For them the forests are sources of food, shelter, and other materials. Even people who live far away what is a rainforest kids tropical rainforests are affected by the forests. Many rainforest plants how to file tax return for foreign income used as medicines to help treat diseases such as cancer.
Scientists believe there are many more plants there that will help treat or even cure serious diseases. In addition, how to unblock on facebook messenger such as fruits, nuts, rubber, rattan, and wood come from rainforests. Tropical rainforests also help to control the water iw of the areas where they grow. They do this by absorbing the constant rain and then releasing it slowly back into the atmosphere.
Some of the water is released steadily into area rivers. Many people rely on the rivers for their water supply and to irrigate their crops. Some of the water is released back into the air through evaporation.
This keeps the air moist and leads to more rain. This important process is called the water cycle. Finally, like all green plants, rainforest plants absorb carbon dioxide gas from the atmosphere and produce oxygen. They do this through the process of photosynthesis. Tropical rainforests grow in many poor countries. Some poor countries sell the wood and other resources of rainforests to make much-needed money.
This often means that entire sections of the forest are destroyed. Rainforests are also cut down or burned away so that the land can be used for other purposes, such as cattle grazing and farming. The rainforests that are destroyed for these reasons are rarely replaced. The loss of rainforests endangers many plants and animals that live nowhere else in the world. Over time, some of these plants and animals may become extinct if their rainforest habitat is destroyed.
When rainforests are cleared, the water cycle is disrupted as well. Rainwater washes away quickly instead of being stored in the plants and returned slowly to the atmosphere. Eventually, rain falls less often, and the region may experience drought. What is a rainforest kids destruction of rainforests also affects the environment of the rest of the world. When forests are burned, raimforest amounts of carbon dioxide escape into the atmosphere. This carbon dioxide contributes to a problem known as global warming.

The forest floor is the bottom layer of the rainforest. This is the area where fallen, decomposing plants and trees lay on the ground. Many insects live here. Temperate rainforests have all of these zones except the emergent layer. The tallest trees in the temperate rainforest canopy grow to . A tropical rainforest is a delicate network of relationships between plants and animals. Many plants, for instance, rely on animals to spread their pollen from flower to flower. At the same time, animals may depend on plants for their food and shelter. In addition, millions of people live in the forests. As you might have guessed from the name, rainforests are forests that get a lot of rain. Tropical rainforests are located in the tropics, near the equator. Most rainforests get at least 75 inches of rain with many getting well over inches in areas. Rainforests are also very humid and warm.
In their branches will be exotic birds such as toucans and macaws, and troops of monkeys will be filling the air with their cries.
Beautiful but deadly predators will be on the prowl—perhaps a stealthy jaguar creeping through the undergrowth, or a magnificent harpy eagle gliding silently between the branches. The scene above describes a lowland tropical rainforest.
All rainforests provide a home for a vast number of species. Despite this, rainforests are under threat, and many rainforest species are becoming endangered.
The biggest threat to rainforests is deforestation for timber. As the name suggests, rainforests are forests that grow in places in which there is a lot of rainfall. How much rain? Well, between and centimetres 79 and in of rain falls annually in a rainforest. The moist and hot environment provides an ideal growing environment for trees and plants, which in turn provide food and shelter for a multitude of animal species. There are two main types of rainforest: tropical rainforests and temperate rainforests.
Tropical rainforests are hot, as well as wet, and are found near the equator all around the world. Temperate rainforests are found in cooler parts of the world, but where there is still high rainfall. There are several different types of tropical rainforest. Often, they merge into each other without definite boundaries.
They occur in non-mountainous regions. Here, much of the land is submerged for at least part of the year. Cloud forests and montane forests are found at high altitudes and are often shrouded in mist. They are cooler than tropical rainforests, and home to a different range of creatures and plants. Rainforests have a number of different layers. Each layer provides a different habitat for a range of species. The emergent layer is the highest rainforest layer. It is where the tops of the tallest trees break out from the surrounding vegetation.
Eagles and other birds survey the forest from the highest perches, and blue morpho butterflies flutter over the trees. The next highest layer is the canopy. It is the treetop layer, being formed by the branches and leaves of most of the trees that grow in the rainforest.
It is around 30 meters feet high. The canopy layer is home to most of the animals that live in the rainforest. It provides shelter and food for an incredible number of species. Plants in the canopy layer tend to have broad, waxy leaves with pointed tips. This encourages rainwater to run straight off, preventing harmful algae and fungi from growing on them. The understory is made up of bushes and shorter trees. It is a dark, hot place. The plants here tend to have large leaves to capture what little sunlight gets through.
Jaguars may laze around in its branches, and boa constrictors lay in wait here, ready to pounce on unsuspecting prey below. Here tapirs wander between the trees, using their snouts to rummage through the soil.
Lines of leafcutter ants form between their huge nests and the trees whose leaves they harvest. Rivers and streams often run through rainforests, draining excess water away and providing yet another habitat for many kinds of animal.
Many animals come to the waterside to drink, and green anacondas slip through the water using their natural camouflage and excellent swimming skills to capture their prey. Tropical rainforests are found near the equator , which is an imaginary line that circles the middle of the globe.
Most of these rainforests are located between the tropics of Cancer and Capricorn, which are two other imaginary lines that run parallel to the equator above and below it. Near the equator there is very little variation in temperature and day length throughout the year. It is hot all year round. However, many places in the tropics have rainy seasons, during which there is even more rainfall than at other times of the year.
The biggest and most famous tropical rainforest is the Amazon Rainforest in South America. It is almost twice the size of India. Temperate rainforests are found further away from the equator, in cooler climates.
They are usually located in coastal regions. The largest temperate rainforest is the Pacific temperate rainforest ecoregion , located along the western coast of northern America from Kodiak Island in Alaska to northern California. The rainforest is an extremely important environment, being home to a vast number of animal and plant species. Mammals, amphibians, reptiles, birds and invertebrates are all present in great numbers. More than 1.
It is likely that there are many millions of species of plants, insects and microorganisms in the rainforest that are still to be discovered.
In South and Central American rainforests , howler and spider monkeys roam the branches, feeding on the abundant fruit growing in the canopy. Harpy eagles hunt in the trees, taking prey as large as sloths and monkeys.
Toucans hop from branch to branch, and brightly coloured macaws catch the eye. On the forest floor, anteaters mop up ants and termites, and predatory mammals such as ocelots and jaguars roam through the trees.
Larger mammals such as deer and tapirs are also present, as are reptiles, including boa constrictors and anacondas. A similarly large range of animals live in other regions. In the rainforests of India , tigers are apex predators. Large animals such as sambar a type of deer and sloth bears live on the forest floor, while birds, including parakeets and the impressive great hornbill share the trees with Macaques, gibbons and lorises. The rainforests on the islands of Borneo, Sumatra and New Guinea are home to several notable endangered species, such as orangutans, proboscis monkeys, clouded leopards and elephant, rhino and tiger subspecies.
These tribes live deep in the forests, away from modern life. However, their way of life is under threat from outsiders who are gradually encroaching on their traditional home. Very few native peoples are completely unaffected by modern life. Many now wear modern clothes and use metal items constructed outside of the forest. However, there are still some tribes whose lives are completely unaffected by the modern world.
It is thought that there are around one million indigenous people living in the Amazon rainforest. Provided they are harvested responsibly, rainforests can provide food, timber and other products useful to man. They also store large amounts of carbon.
If the rainforests are destroyed and left to rot, the carbon can be released as carbon dioxide — a harmful greenhouse gas. Rainforests are beautiful places, and our quality of life is improved by their presence.
Even if we never actually get to walk in a rainforest, we can see pictures of them, and learn about the animals and plants that live in them. Because this benefit cannot be measured, it is often overlooked, but it is another important reason that rainforests — and all wild places — are important.
Sadly, rainforests are under threat all over the world. Most of the trees are cut down for timber. This is used in building, and also for power production and for paper. Rainforests are also destroyed to make way for farms. The trees are cut down to make fields, in which crops such as sugar cane and oil palm trees are grown, and livestock kept. Predatory rainforest animals are sometimes hunted by farmers wishing to protect their livestock.
In this article we have found out all about rainforests. We have found out what they are, where they are located, the animals and people that live in them and why we need to protect them.
