Question

Which of the following process relates to the abiotic components of an ecosystem?

• A. Flow of energy
• B. Cycling of material
• C. Consumer
• D. Flow of energy and cycling of material

Answer 1

Answer: (B)

Cycling of material

Any ecosystem has two components -biotic or living organisms and abiotic or non living component.

Further, two most important functional characteristics of any ecosystem are unidirectional flow of energy and cycling of material. The living organisms of a ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. Energy is transferred from one trophic level to the next through the food chains.

Decomposers release the nutrien back into the environment, which are trapped in dead and decaying organic matter. Therefore the correct answer is option B.
