19 paź 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.

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). It is not the same as a food web.
Food chains show the flow of energy from one organism to another. Food chains show the feeding relationships between organisms. Food webs show how all the food chains in an ecosystem interact.
31 paź 2023 · 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.
What is a food chain? Describe the role of decomposers in food webs. Why is a food web more realistic than a food chain? Draw a terrestrial food chain that includes four feeding levels.
15 cze 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.
31 lip 2022 · 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. There is a single path through the chain.
