A rain forest is found in a tropical climate close to the Equator. A tropical rain forest receives more than 80 inches of rain a year. It is also home to a huge variety of plants and animals. In fact, over half of all the plants and animals are found in a rain forest. Contrary to what most believe, a rain forest is not always good place to grow crops or raise animals. The plants & large trees grow up and form a canopy at the top. This canopy allows little sunlight in. Also, large amounts of rain at one time can flood crops or wash away seeds that have been planted.
However, a rain forest has many other amazing resources to offer. Over 25% of natural medicines have been discovered in rain forests.
At one time, rain forests covered 14% of the world's surface. Now due to deforestation they only cover 6%. Deforestation is cutting down or clearing the trees on a large scale. At one time, countries damaged or destroyed rain forests by using them for natural resources to sell and make money. Today, countries are taking special care of their rain forests so they are not completely destroyed.
The emergent layer has high tree tops that rise above everything else. It gets the most sun and rain and is much windier than other levels so it isn't the best place for animals to call home. The tallest trees can reach 230 feet. Colorful birds and butterflies fly above the trees. Small mammals also swing through the branches.
The canopy is made up of thick branches and leaves of tall trees. It is sunny and wet. The thick branches form an umbrella over the layers below. These branches block 70% of sun and rain from reaching the floor. More plants and animals live in this layer than any other. This is also the loudest layer with animals making lots of noise, especially birds. Many animals fly from tree branch to tree branch like monkeys and sloths.
The understory is made up of small, thin trees and leafy shrubs. These smaller trees and bushes help fight erosion which is when the rain causes soil to be washed away. It is warm, damp, and sheltered in this layer. Large predators might climb and hide here to pounce on their prey like jaguars and leopards.
The floor is the darkest and dampest layer, only 2% sunlight reaches this level. Dead leaves cover the ground. Many insects and fungi can be found here s well as the largest animals like jaguars or tigers. It is also the quietest layer as animals sneak around in the dark making very little noise.
