Which term describes the network of organisms and their feeding relationships in an ecosystem?

• A. Food web
• B. Food chain
• C. Ecosystem
• D. Habitat

Answer: (A)

The main idea is understanding how energy moves through living things in an area via feeding relationships. The network of who eats whom in an ecosystem is a food web. It includes many connections among producers, herbivores, predators, and decomposers, showing how energy and nutrients flow through a community in multiple interlinked paths. This makes a food web more representative of real ecosystems than a single linear path, which is what a food chain shows. An ecosystem refers to the whole system of living organisms plus the environment, not just the feeding relationships, while a habitat is the place where an organism lives.
