Explanation:

Part (a)

A food chain shows the flow of energy from producers to consumers. Algae are producers (they make their own food via photosynthesis). Limpets eat algae, so limpets are primary consumers. Crabs eat limpets, so crabs are secondary consumers. So the food chain is algae → limpets → crabs.

Answer:

algae → limpets → crabs
