Food Chain Definition Class 10

The chain of organisms which involves transfer of energy from one trophic level to next trophic level is called as food chain.

Food chain definition class 10. A food chain explains which organism eats another organism in the environment. This maintains a check on the population and a balance in the ecosystem. The definition of food web is a model of food chains that intersect and show what eats what.

Food chains describe the feeding relationship between the organisms of an ecosystem. In a community which has producers consumers and decomposers the energy flows in a specific pathway. Food Chain Food chain tells us how energy is transferred from one organism to another.

A food chain refers to the order of events in an ecosystem where one living organism eats another organism and later that organism is consumed by another larger organism. The linear sequence of organisms where one is consumed by the other for food is known as a food chain. As a result a situation of eating and being eaten exists.

Grazing food chain It starts with autotrophs and goes to consumers. Fundamentally the food chain is the sequence of organisms where the transfer of matter and energy takes place in the form of food from organism to organism. Class 10 Biology Our Environment Food web Each organism is generally eaten by two or more kinds or organisms which are again eaten by several other organisms and so instead of straight line food chain the series of organisms dependent on one another food can.

In other words it is a list of who eats whom in a biotic community. Food chain is a sequence of organisms in a biotic community through which food passes with members of a step becoming food of the members of the next step of the sequence. A food chain explains which organism eats another organism in the environment.

It is a longer food chain. A food chain is a series of organisms where all the organismsare dependent on next organism as a source of food. The series of organism take part at various biotic levels to form a food chain.
