Which model shows the complex network of feeding relationships within an ecosystem?

• A. Biomass
• B. Trophic level
• C. Food web
• D. Hydrologic cycle

Answer: (C)

Understanding how energy and nutrients move through ecosystems depends on seeing feeding relationships as an interconnected network. A food web shows all the feeding links among organisms in a community, with producers, herbivores, carnivores, omnivores, and decomposers connected in many paths. This network perspective explains how energy flows along multiple routes and how changes to one species can ripple through the system. The other terms refer to different ideas: biomass is about the amount of living material at each level, not who eats whom; a trophic level is simply a position in the food chain (such as producer or primary consumer); and the hydrologic cycle describes water movement, not feeding interactions.
