Verified by Experts
The correct answer is:
D

Decomposers (such as bacteria, fungi, and other microorganisms) have the largest population in a food chain because they are responsible for breaking down the remains of all organisms at every trophic level. Their sheer numbers are astronomical compared to macroscopic organisms due to their microscopic size and rapid reproduction rates.
