Which term best describes the network of feeding relationships among organisms within an ecosystem?

• A. Fauna
• B. Habitat
• C. Germination
• D. Ecosystem

Answer: (D)

Energy flow and interactions among living things happen within an ecosystem, which is the system that includes both organisms and their physical environment. The network of feeding relationships—who eats whom and how energy moves through the community—is a set of interactions that sits inside that broader system. So, describing the overall network of these interactions as part of an ecosystem makes sense because the term captures both the living components and their connections with the environment. Fauna is just the animal life in a region, not the network of relationships. Habitat is the place where organisms live. Germination is the process of a seed sprouting.
