food chain

Sequence of organisms in an ecosystem occupying specific hierarchical levels (trophic levels) such that organisms belonging to a superior level survive by eating organisms belonging to inferior levels. The chain begins with plants and ends with the largest carnivores. The sequence can be represented as compartments in a mathematical model or analysis.
