What term describes a model that shows what eats what in an ecosystem?

• A. Indirect effect
• B. Food web
• C. Stability
• D. Resource population

Answer: (B)

A model showing who eats whom in an ecosystem is a food web. It maps the network of feeding relationships among producers, herbivores, and various levels of consumers, illustrating how energy moves through an ecosystem. Food webs capture multiple pathways and potential indirect effects, unlike a single food chain which shows only one linear path. The other terms describe specific ideas rather than the whole network: an indirect effect is about how one interaction influences another through a chain; stability refers to how resistant or resilient the ecosystem is to change; and resource population means the amount of available food resources, not the network of who eats whom.
