food chain is a collection of organisms who eat and are eaten by other organisms.
For example grass is eaten by grass hopper,then snake eats this grass hopper, then again this snake is eaten by a hawk and when this hawk dies,fungi decomposes it. so a cycle continuously occurs and the energy is not destroyed but is used by other organisms.
