The primary consumer may be eaten by a secondary consumer, which in turn may be consumed by a tertiary consumer. The food chain begins with a producer, which is eaten by a primary consumer.

The food chain is an energy source diagram. The mean chain length of an entire web is the arithmetic average of the lengths of all chains in the food web. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web. Natural interconnections between food chains make it a food web.Ī common metric used to quantify food web trophic structure is food chain length. A food chain differs from a food web because the complex network of different animals' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time. Each level of a food chain represents a different trophic level. A food chain also shows how organisms are related to each other by the food they eat. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceansĪ food chain is a linear network of links in a food web starting from producer organisms (such as grass or algaes which produce their own food via photosynthesis) and ending at an apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria).
