Question

which best describes the flow of energy through a food chain?
a. sunlight → producers → consumers → decomposers
b. decomposers → producers → consumers → sunlight
c. producers → sunlight → consumers → decomposers
d. producers → decomposers → consumers → sunlight

Explanation:

In a food chain, energy flow starts with sunlight. Producers (like plants) capture sunlight via photosynthesis. Then consumers (herbivores, carnivores) eat producers or other consumers. Finally, decomposers break down dead organisms, recycling nutrients. Option A follows this order: Sunlight → Producers → Consumers → Decomposers. Other options misorder the flow (e.g., B starts with decomposers, C has producers before sunlight, D has incorrect order).

Answer:

A. Sunlight → Producers → Consumers → Decomposers
