Definition a feeding hierarchy in which organisms in an ecosystem are grouped into trophic (nutritional) levels and are shown in a succession to represent the flow of food energy and the feeding relationships between them.

In a community which has producers, consumers, and decomposers, the energy flows in a specific pathway. A food chain begins with a producer, usually a green plant or alga that creates its own food through photosynthesis. The consumers include all the other types of organisms in the ecosystem like herbivores, carnivores etc.
