Question

Which of the following occurs in abiotic component of ecosystem?

• A. Flow of energy
• B. Cycling of materials
• C. Consumers
• D. Flow of energy and cycling of materials

Answer 1

The correct option is D Flow of energy and cycling of materials

Flow of energy and consumers are part of biotic components of ecosystem. Water, carbon, nitrogen and phosphorous all take paths from the non-living environment to living organisms, such as trees and then back to non-living environment. These paths known as biogeochemical cycles. In these cycles, a pathway is formed when a substance enters into living organisms, stays for a long time, then returns to the non-living environment. As it is part of abiotic component of ecosystem.

Therefore, the correct answer is option B.
