A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.
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 ).
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Let's look at the parts of a typical food chain, starting from the bottom—the producers—and moving upward.
Oct 19, 2023 · The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales ( Balaenoptera musculus )—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight.
Jun 15, 2023 · A food chain is a group of organisms that are consumed in a linear order, passing nutrients and energy along the way. Each organism in a food chain is at a particular trophic level, which is determined by how many energy transfers distance it from the chain’s primary energy source.
May 29, 2024 · Food web, a complex network of interconnecting and overlapping food chains showing feeding relationships within a community. A food chain shows how matter and energy from food are transferred from one organism to another, whereas a food web illustrates how food chains intertwine in an ecosystem.
