What is Food Chain?

Toggle navigation. Language English. Food chains and food webs Black-crowned night-heron. This predator is adapted to hunt at night. In the French Guiana this is one of the major night heron species with its cousin the Yellow-crowned night-heron Nycticorax violacea. Feeds mainly on aquatic animals, including fish, amphibians and insects.

A food chain is a linear network of links in a food web starting from producer organisms such as grass or trees which use radiation from the Sun to make their food and ending at apex predator species like grizzly bears or killer whales , detritivores like earthworms or woodlice , or decomposer species such as fungi or bacteria. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level. 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. Natural interconnections between food chains make it a food web. A common metric used to the quantify food web trophic structure is food chain length.

Food chains and webs show how food and energy are passed between species. Food Chain A food chain is a food pathway that links different species in a community. In a food chain, energy and nutrients are passed from one organism to another. Food Chains rarely contain more than six species because amount of energy passed on diminishes at each stage, or trophic level. The longest chains usually involve aquatic animals. In a food chain, an animal passes on only about 10 percent of the energy it receives.

All living organisms depend on one another for food. By reviewing the relationships of organisms that feed on one another, this lesson explores how all organisms— including humans—are linked.

All matter is conserved in an ecosystem, but energy flows through an ecosystem. This energy moves from one organism to the next in what is known as a food chain. All living things need nutrients to survive, and food chains show these feeding relationships. Every ecosystem on Earth has many food chains that include a variety of organisms. A food chain shows energy pathways in ecosystems. Each ecosystem on the planet has food chains of organisms ranging from producers to consumers. The producers are on the lowest level of the food chain, while the consumers that eat those producers are called primary consumers.

A Food chain can be defined as the feeding relationship between the different organisms that make up our ecosystem. An ecosystem is a commune of living organisms. The ecosystem also includes the non-living components like, earth, water, fire, air and ether. The living and non-living together form the environment. Within the environment , the living or the biotic components need food for survival.
