Which term describes the network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem?

• A. Food chain
• B. Food web
• C. Detritus cycle
• D. Trophic pyramid

Answer: (B)

Feeding relationships in a community form an interconnected network where many species interact as predators, prey, and decomposers, creating multiple energy pathways. This broad, branching pattern is best described as a food web because it shows how more than one species can affect another and how energy moves through the community through several routes. A food chain, by contrast, traces a single linear path from one producer to one consumer, which is a simplification not reflective of most ecosystems. The detritus cycle focuses on decomposition and nutrient recycling by detritivores and decomposers, not on who eats whom. A trophic pyramid represents the distribution of energy or biomass across levels, typically as a simple triangle, rather than the actual network of feeding connections. Thus, the network of feeding relationships is a food web.
