What is the difference between food chains and food webs?
Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers.
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

The second statement is correct.

- Food chain: a single linear pathway showing how energy and matter flow from one organism to the next (e.g., grass → grasshopper → frog → snake → hawk).
- Food web: a network of many interconnected food chains showing multiple, overlapping feeding relationships in an ecosystem (e.g., grass eaten by rabbits and grasshoppers; rabbits eaten by foxes and owls; foxes also eat mice, etc.).

Why the first statement is wrong: energy always flows from producers (plants/autotrophs) up to consumers; it does not flow “from consumers to producers.” Food webs are simply the more realistic, complex representation of energy flow compared with the simplified, single-path view of a food chain.
