Question

Nutrients present in plants and animals are used again and again with the help of

• A. Consumers
• B. Decomposers
• C. Producers
• D. Man

Answer 1

Answer: (B)

Decomposers

Bacteria and fungi are considered as the decomposers in the ecosystem. They degrade the biodegradable substances present in the environment for obtaining their food with the help of the specific enzymes.Decomposers also help in maintaining the nutrient pool by adding back various elements like carbon, nitrogen etc. (formed during decomposition) into the nutrient pool to continue the biogeochemical cycles. During the process of decomposition, complex organic compounds are broken down into simple inorganic compounds which go into the soil and are utilised by the plants. As dead remainings of plant and animals are degraded in the process, decomposers act as a cleansing agent of nature. They also add humus to the soil which increases the soil fertility.

So, the correct option is A.
