Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to the food chain.
Interconnection of the food chain will form the food web.
Animals dwelling in the forest help it grow and regenerate in the following ways :
(1) Animals help in dispersing plant seeds.
(2) Decaying animal dung provides nutrients for plants to grow.
(3) Microorganisms convert the dead plants and animals to humus.
