Food Chain Definition Environmental Science

A food chain always starts with a producer an organism that makes food.

Food chain definition environmental science. It begins with producer organism follows the chain and ends with decomposer organism. A food chain describes the feeding relationships of different organisms in a linear fashion. Fōōd the sequence of the transfer of food energy from one organism to another in an ecological community.

The dead organic substances are decomposed by microorganisms. Plants which convert solar energy to food by photosynthesis are the primary food source. An animal that feeds on dead organic material especially plant.

Food chain in ecology the sequence of transfers of matter and energy in the form of food from organism to organism. In scientific terms a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other. A food chain explains which organism eats another organism in the environment.

Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. The definition of a food chain is a system where a small animal is the food for a larger animal which in turn is the food for an even larger animal. Most ecosystems contain.

Each of several hierarchical levels in an ecosystem comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy. 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 bacteriaa food chain also shows how the organisms are related with. In a predator chain a plant-eating animal is eaten by a flesh-eating animal.

It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th. In a community which has producers consumers and decomposers the energy flows in a specific pathway. A food chain is a pathway that represents the exchange of energy from one organism to another.
