A food chain represents a single pathway by which energy and matter flow through an ecosystem. an example is shown in figure below. food chains are generally simpler than what really happens in nature. most organisms consume—and are consumed by—more than one species. this food chain includes producers and consumers. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. each organism in a food chain occupies a specific trophic level (energy level), its position in the food chain. the first trophic level in the food chain is the producers. Food chains. a food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher level consumers, and finally decomposers. these levels are used to describe ecosystem structure and dynamics.
