उत्तर
Forests work as a self-sustaining system in nature. Whatever is produced in the forest is utilised by different components of the forest and is naturally recycled. All animals (whether herbivores, carnivores or omnivores) depend ultimately on plants for food. Herbivores eat plants. Carnivores eat herbivores. Omnivores eat both plants and animals. When plants and animals die, their dead remains are decomposed by microorganisms (bacteria and fungi) into nutrients, which are released back into the soil. From the soil, these nutrients are absorbed by the roots of living plants. This is called as recycling of nutrients due to which nothing goes waste in a forest.
