(b) Because plants are nutritious

(d) Because plants do not require energy

This question was addressed to me during an internship interview.

The above asked question is from Food Chains in section Ecosystems of Energy Management

Answer 1

Right option is (c) Because plants can produce its own energy

For explanation: The whole food chain depends on the producers. Plants are the only producers. The plants are autotrophs, as they produce their own food by the process of photosynthesis. Food is the source of energy in living being, thus plants are required to start food chains.
