the correct sequence of energy flow in a simple food chain is:
sun → producers → consumers → decomposers
decomposers → producers → consumers
producers → consumers → sun
consumers → producers → sun

Explanation:

In an ecosystem, the sun is the primary source of energy. Producers (like plants) use sunlight for photosynthesis to make food. Consumers (herbivores, carnivores, etc.) eat producers or other consumers. Decomposers (bacteria, fungi) break down dead organisms (producers and consumers) and recycle nutrients back to the environment. So the energy flow is from the sun to producers, then to consumers, and finally to decomposers.

Answer:

Sun → Producers → Consumers → Decomposers
