Food Chain Definition Environmental Science

Every living thingfrom one-celled algae to giant blue whale sneeds food to survive.

Food chain definition environmental science. Food chain. Food chain definition a series of organisms interrelated in their feeding habits the smallest being fed upon by a larger one which in turn feeds a still larger one etc. A food chain is organized into trophic levels which are levels that show where an organism obtains its energy.

A food chain is a pathway that represents the exchange of energy from one organism to another. 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. These detritivores are later eaten by.

The chain of organisms which involves transfer of energy from one trophic level to next trophic level is called as food chain. Each food chain is a possible pathway that energy and nutrient s can follow through the ecosystem. For example grass produces its own food from sunlight.

It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th. This is usually a green plant because plants can make their own food by photosynthesis. 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.

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. 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 is one of the most interesting topics of Science and elucidates upon how every living being is connected together in an ecosystem.

This is the simplest way of showing feeding relationships. 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. The flow of food or energy in an ecosystem is called food chain.
