Leaves+and+Trees



Trees and leaves play an important role in our lives. Trees provide homes and food for birds and animals, and wood to build homes and keep us warm. Besides being beautiful, leaves produce food for the trees. They have openings that allow the air to come in and go out, and remove the carbon dioxide from the air and release oxygen back into it. This is part of a process called photosynthesis. Factmonster will tell you more about about trees and leaves.
