Question

To which trophic level do the earthworms belong in a food chain?

• A. Primary consumers
• B. Secondary consumers
• C. Scavengers
• D. Decomposers
• E. Producers

Answer 1

The correct option is D Decomposers

The autotrophic organisms make their own food by photosynthesis. Primary consumers feed on producers. Secondary consumers feed on primary consumers. Scavengers feed on dead animals and plants parts while decomposers feed on debris left behind by scavengers and release the nutrients in form of simpler substances back to the atmosphere. Earthworm feed on decaying organic matter present in soil and release the nutrients thereby serving as a decomposer. Thus, the correct answer is D.
