A sequence that represents the series of eating and being eaten is called [[1]].

A food chain is a linear sequence of organisms in which each organism serves as a source of food for the next. It is a possible pathway in which energy and nutrients can flow through the ecosystem. A community of living and nonliving things that interact with one another in a specific environment is referred to as an ecosystem.

A food chain is a part of a more complex web of relationships called a food web, where organisms can have multiple predators and prey and not all organisms are consumed by others.

For example, the grass produces its own food from the sunlight and the rabbit eats the grass which in turn is eaten by carnivores.
