A food chain is a series of distribution of energy in the form of food, when one organism is eaten up by the other organism. A producer is an organism which produces it own food and source of energy either from simple chemical substances like chemosynthesis or by utilizing the light energy from the sun, in the presence of water and carbon dioxide that is through photosynthesis.

A consumer is an organism which is incapable of producing it's own food, and depends upon the producers and other consumers for their food and energy requirements.
