3. Explain : Decomposers play a crucial role in the food chain.
Answers
Answer:
Decomposers are organisms that break down the dead organic matter into simpler substances to release energy and nutrients. They play an important role in the conduit of energy and nutrients in an ecosystem. By carrying out nutrient recycling, they make it available for uptake by plants.

Explanation:
Every part of an ecosystem is vital to its survival – from the green plants to furry animals and microscopic bacteria. The group of organisms called decomposers forms the final link in the food chain. They break down dead animals and plants and return vital nutrients to the soil . At the end of the chain, decomposers act as the “clean-up crew” – they consume dead animal carcasses, decaying plant material and waste products from other members of the ecosystem. Earthworms, for example, take in soil and microorganisms and excrete waste filled with nutrients, which are added to the soil. Fungi absorb nutrients from the plants and animals they consume while releasing enzymes that break down dead organic matter.
