Food Chain Definition Biology

The transfer of food energy from the source in plants through a series of organisms with repeated eating and being eaten is known as a food chain.

Food chain definition biology. A food chain almost always begins with a green plant (producer) which is eaten by an animal (consumer). In the example, grass seeds are eaten. The food chain starts with the producer or plants that convert solar energy into the usable form of energy (food) by the process of photosynthesis which is then eaten by consumers.

In contrast, food web is a complex pathway that indicates a number of food chains together to show how the organisms are interlinked with each other to survive. “it is the process by which nutrients are transferred between the different species that make up a biological community.

Toxins from environment may enter organisms during respiration or feeding. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. In biology and ecology, we use the terms food web and food chain.

It begins with producer organism, follows the chain and ends with decomposer organism. A food chain also shows how the organisms are related with each other by the food they eat. Food chains and food webs.

Food may be derived from another living thing through predation, parasitism, etc. How food chains and food webs represent the flow of energy and matter. The sequence of who eats whom in a biological community.

For most photosynthetic plants, their food is the product of their own photosynthesis whereas many animals depend on the plants as their direct food. The grazing food chain begins with producers like green plants, who create their own food through the process of photosynthesis and later move from herbivores to carnivores. Or the transfer of energy from one trophic level to the next trophic level is called food chain.
