Food Chain Definition Environmental Science

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 an apex predator species like grizzly bears or killer whales detritivores like earthworms or woodlice or decomposer species such as fungi or bacteriaA food chain also shows how organisms are related to each.

Food chain definition environmental science. A food chain explains which organism eats another organism in the environment. When two or more than two types of food chains get connected or interlinked with each other then they form a food web. The food chain can also end one step further with decomposers like bacteria or worms which would process the predator species once it dies depending on the definition.

The proper functioning of the food chain is crucial for healthy development of species on our planet. For example grass produces its own food from sunlight. The dead organic substances are decomposed by microorganisms.

A food chain describes the feeding relationships of different organisms in a linear fashion. A simple sequence of transfer of energy in the form of food from one tropic level to another in a linear fashion is known as a food chain. On average food chains include around five trophic levels.

Food chain definition environmental science. Food chain in ecology the sequence of transfers of matter and energy in the form of food from organism to organism. Learn vocabulary terms and more with flashcards games and other study tools.

Start studying AP Environmental Science Food Chains and Food Webs. A food chain always starts with a producer an organism that makes food. The organisms that feed on dead organic matter or detritus are known as detritivores or decomposers.

In a predator chain a plant-eating animal is eaten by a flesh-eating animal. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. It begins with producer organism follows the chain and ends with decomposer organism.
