Food Chain

A food chain refers to the sequence of organisms in an ecosystem where each organism is the source of food for the next. It demonstrates the flow of energy and nutrients in a particular ecosystem.

Examples:

The grass is eaten by a rabbit, which is then preyed upon by a snake, creating a food chain.
In the ocean, the food chain typically starts with phytoplankton, which is consumed by small fish, then larger fish, and finally by marine predators.
The lion is at the top of the food chain in the African savannah.
