What diagram illustrates the feeding relationships between organisms in an ecosystem?

A food web is the diagram that illustrates the feeding relationships between organisms in an ecosystem. It comprises many interconnected food chains, showing how different species are linked through their dietary habits. This complexity reflects the reality of ecosystems, where organisms often have multiple food sources and predators, creating a network of interactions.

On the other hand, a food chain represents a linear sequence of who eats whom, simplifying the relationships to a single pathway. An energy pyramid depicts the energy distribution among trophic levels in an ecosystem, while a biogeochemical cycle involves the movement of elements through biological and geological processes. Therefore, a food web is the most comprehensive representation of feeding interactions among various organisms, highlighting the intricate connections that sustain an ecosystem.
