Question

Quizplus · Accepted Answer

In a typical aquatic food chain, algae, which are primary producers, are eaten by primary consumers such as insect larvae. These larvae are then consumed by secondary consumers like fish, which can be eaten by tertiary consumers, such as humans. This sequence (A) represents a plausible flow of energy from the lowest trophic level (algae) to the highest (humans).
