Question

Energy and nutrients enter a community by

• A. Primary consumer
• B. Producer
• C. Decomposer
• D. Sunlight

Answer 1

Answer: (B)

Producer

In any ecosystem, producers occupy the first trophic level. The producers trap solar energy and convert its light energy into biologically useful organic compounds like sugars. Thus, green plants also act as energy converters. They convert light energy of the sun into chemical energy of sugars. The sugars synthesized by the producers are consumed by herbivores and herbivores are consumed by carnivores. In this manner, green plants are the source of energy and nutrients to all the organisms in an ecosystem.

Thus, the correct answer is option B.
