Forests are excellent, perfect and natural recycling factories. All animals, whether herbivores or carnivores, depend ultimately on plants for food. Herbivores eat plants and their products. Carnivores eat herbivores. *** of animals and plants are decomposed by micro-organisms into humus. Whatever is produced in the forest is ultimately utilized by different components of the forest. Forests maintain a network of food chains called food web and hence nothing goes waste in a forest.
