19. Okt. 2023 · Learn how food chains describe who eats whom in the wild and how energy and nutrients flow through ecosystems. Explore different types of trophic levels, examples of food chains, and the role of decomposers.
A food chain is the sequence of transfers of matter and energy in the form of food from organism to organism. Learn about different types of food chains, such as predator, parasite, and saprophytic chains, and how they intertwine into a food web.
- The Editors of Encyclopaedia Britannica
A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae ), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales ), detritivore (such as earthworms and woodlice ), or decomposer (such as fungi or bacteria ).
5. Apr. 2024 · A food web is a complex network of interconnecting and overlapping food chains showing feeding relationships within a community. Learn how food webs illustrate how energy and matter are transferred and cycled among producers, consumers, detritivores, and decomposers in ecosystems.
Learn how food chains and food webs represent the flow of energy and matter in ecosystems. Explore the roles of producers, consumers, and decomposers, and the efficiency of energy transfer between trophic levels.

The scientific understanding of a food chain is more precise than in its everyday usage. In ecology, a food chain is a linear sequence of organisms through which nutrients and energy pass: primary producers, primary consumers, and higher-level consumers are used to describe ecosystem structure and dynamics.
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 ...
