Which term describes a network of feeding relationships formed by multiple food chains?

• A. Grazing food chain
• B. Food chain
• C. Food web
• D. Ecosystem

Answer: (C)

Feeding relationships organize energy flow in a community. When several chains connect because species have more than one prey or predator, these links form a network—the food web. The key distinction is that a food chain shows a single linear sequence of who eats whom, whereas a web captures many interconnections and overlaps. A grazing food chain is one such chain that starts with producers and follows herbivores and their predators; it’s still just a line, not the whole network. An ecosystem refers to the entire living community plus its physical environment, not specifically the pattern of feeding links. Therefore, the network of feeding relationships formed by multiple food chains is a food web.
