Notes:
Plants provide human beings and other animals with food and
oxygen. On the other hand, animals and human beings breathe
out carbon dioxide which is taken by plants for preparing their
food.So plants and animals depend on each other for their
survival. Nature maintains a balance between the number of
plants and animals, which helps in the existence of life on the
earth.
