Food Chain And Food Webs Explained A food chain is a network of links in a food web. here, the producers are consumed by the predators primary and secondary consumers and then the detritivores and finally by decomposers. when many such individual food chains occur in an ecosystem, it is known as food web. a food chain shows a direct transfer of energy between organisms. A food chain outlines who eats whom. a food web is all of the food chains in an ecosystem. each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. primary consumers, mostly herbivores, exist at the next level, and secondary and.
Trophic Pyramid Definition Examples Britannica A food web is a graphic representation of a holistic, nonlinear web of primary producers, primary consumers, and higher level consumers used to describe ecosystem structure and dynamics (figure 1). figure 1. example of simplified food chains (a) and food webs (b) of terrestrial and marine ecosystems. Tertiary consumers eat secondary consumers and are found at the last or the fourth trophic level. in deserts, an owl or an eagle is a tertiary consumer eating a snake. there are more levels of consumers above the tertiary consumers. apex consumers residing at the top of the food chain are organisms that feed on other consumers for food. Learn how to identify producers, consumers, and decomposers in a food web with this worksheet. see examples of food webs for a forest and an aquatic ecosystem and create your own. 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.
