Work Step by Step
Tropical rain forests, lying close to the equator, are warm and humid. They receive much rain throughout the year. This generous amount of rain sustains the growth of trees and lush vegetation. With the various types of plant life, other organisms find food and shelter. Many of the organisms that live in tropical rain forests make their homes in the trees. Even the soil found on the floor of tropical rain forests is rich with life; this soil is home to bacteria and other microscopic organisms that cause the decomposition of dead matter.
