A food chain represents one pathway by which Strength and make a difference flow by an ecosystem. An instance is shown in Determine beneath. Food chains are frequently less difficult than what genuinely comes about in character. Most organisms eat—and so are eaten by—more than one species.

During the Environmentally friendly procedure point out, both of those copepods and microzooplankton exert a solid grazing tension on phytoplankton, though during the Blue point out, copepods raise their predation about microzooplankton, which consequently shifts its predation from phytoplankton to bacterial plankton or picoplankton. These trophic mechanisms stabilize the shipping and delivery of organic matter from copepods to fish. Food webs are extremely elaborate.
