Food chain is a sequence of organisms in an ecosystem, in which, each species is the food of the next member of the chain.
Look at the following figure of the food chain
Here it has been shown how nutrients, after synthesizing in plants body, are transferred from one organism to another.
Food chain are composed of many components like producer and consumer.
Let us study them in detail.
Producers are those, which can synthesize food using carbon dioxide and water.
All the green plants are producers.
Animals and insects are consumer because they all, directly or indirectly, depend on plants for their food , On the basis of food that the animals take in, they have been classified into three groups, that is, herbivorous, carnivorous and omnivorous.
Animals of this group feed on only green plants. In other word plant eating animals are called herbivorous. For example, buffalo, cow, camel etc.
Animals of this group feed on only flesh of other animals. In other words, flesh eating animals are called carnivorous. For example lion, tiger, fox, etc.
Animals of this group feed on both plants and flesh. For example, human, bear etc.
