Plants also provide the animals with shade and shelter.
They act as supports for the eggs of animals especially insects. Plants make food from the carbon and other things that come from animals' bodies.

Birds and other animals eat the fruit in which seeds grow and often drop the seeds where they can sprout into new plants. So animals help make new plants grow.
