Question

Which statement is correct about the role of decomposers in the environment?

• A. Decomposers break down the dead and decaying organic matter.
• B. Decomposers return the nutrients to the soil.
• C. Decomposers play a very important role in the nutrient re-cycling.
• D. All of the above.

Answer 1

Answer: (D)

All of the above.

Decomposers are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals. As the decomposers feed on the dead animals, they break down the organic compounds into simple nutrients to the soil. Organic matter is recycled in an ecosystem by decomposers.
