What is the difference between a food web and a food chain?

• A. A food chain shows multiple interconnected feeding relationships; a food web is linear.
• B. A food web shows multiple, interconnected feeding relationships; a food chain is a single linear sequence.
• C. They are the same.
• D. A food web includes only producers.

Answer: (B)

Understanding how feeding relationships are organized in ecosystems helps distinguish between a food chain and a food web. A food chain is a single, linear sequence showing energy transfer from one organism to the next in a straightforward path—for example, grass → rabbit → fox. It’s a simplified line of who eats whom. A food web, in contrast, maps many interconnected feeding relationships within a community. Most organisms have multiple prey and can be prey for multiple predators, creating a network of feeding links. This interconnected web shows how energy moves through an ecosystem in several possible paths and explains how changes in one species can affect many others. So the difference is that a food web is a complex network of feeding relationships, while a food chain is a single, linear sequence.
