Correct Answer
D
1, 2, 3, 4 and 5
Explanation
Option (c) is correct because earthworms, millipedes, and woodlice are detritivores that obtain nutrients by consuming detritus (dead and decaying organic matter). Jellyfish and seahorses are carnivores that feed on live prey, making option (d) the most common error for those who fail to distinguish between decomposers and active predators. The core concept tested is the functional classification of organisms based on their feeding mechanisms and roles in the ecosystem's energy cycle.
