A food chain is a linear series of links starting with one specific species that eats no other species in the web, and endling with a specific species that eaten by no other species in the web.That's different from a food web.

All living things need food to have energy which help them to grow and move.A food chain tells how each living thing gets its food and how most of living beings are dependent on each other for their energy requirement.It is also called food web or energy pyramid.A food chain always starts with a producer, which in most of the cases is a plant and it ends with a predator,it is at the top of the food chain.
