Expert Answer:

Food chain is a series of organisms linked by their feeding relationships, through which food energy is passed in an ecosystem.

A sequence of organisms is formed here, each of which uses the next, lower member of the sequence as a food source. For e.g. a plant is eaten by a small fish, which is eaten by a larger fish, which is eaten by a bird, and so on.
