Food chain is the basic circle of life.
It depicts how each species, each category of existence, is dependent on other category/species for their survival.
It starts from plants, how cattles and other animals like deer, etc., are dependent on plants, other animals like lion, etc., who have a carnivore diet, are dependent on these lower belt of animals.
Similarly, human beings are also dependent on plants, those who are herbivores. On the other hand, their are human beings, who are omnivores. These depend upon flesh, meat too.
I hope this answer helps!😊

Food chain is the process of who eats whom . It is the cyclic process of eating where large animal feed on small one and small animals feeds on resources available or on anything .
For example :-
Grass– grasshopper– frog–snake — vulture .
Here , grasshopper feeds on grass , frog eats grasshopper and further eaten by snake and lastly snake is eaten by vulture. Here the cycle of who eats whom can be clearly defined . Here grasshopper is primary consumer and vulture is highest consumer .
This food chain is very important for maintaining the balance of environment if this process will stop the organism will not survive due to shortage of food. Also the number of species will be increasing rapidly day by day.
Thus, food chain maintenance the number of species. Several food chains will constitute one food web where one animals can be eaten by several animals .
Hope you will be satisfied with my answer.
Thank you!!

Food chain is a link of organisms through which energy is transferred in the form of food by the process of one organism consuming the other. it describe the relationship of organisms about ‘who eats whom’.
Each step a level of the food chain forms are trophic level. The producers (autotrophs) are at the first trophic level. They fix up the solar energy and make it available for consumers (hetrotrophs). The herbivorous or the primary consumers have at second, small carnivorous or secondary consumers are the third and large of the tertiary consumers form the fourth trophic level.
Food chain shows how food and energy passes from one organism to another in a habitat. Arrows in the food chain indicates the direction in which the energy flows in an ecosystem. It is the one way process that is undirectional flow of energy. The energy captured by organism of a particular trophic level does not revert back to the previous trophic level. Each food chain is the possible pathway that energy and nutrition can flow throughout the ecosystem. A simple food chain in a grassland ecosystem could be
Grass -> Shree -> owl.
In this food chain grass is the primary producer. The grasshopper is a primary consumer which utilise the ATP produced during photosynthesis in produces. ATP stored in food matter, which is utilised by this plant eater that is herbivores. The Shrew is a secondary consumer and the Owl is a tertiary consumers. Food chains are of two types. The chain is based on living plant and it is termed as a grazing chain and the one based on a dead plant material it is that detrial chain or a decomposer chain.
