What is a food chain in science definition?

Answer 1

Food chain is defined as the feeding relationships between species to another within an ecosystem. Organisms are connected to the organisms they consume by arrows representing the direction of biomass transfer. Typically a food chain or food web refers to a graph where only connections are recorded, and a food network or ecosystem network refers to a network where the connections are given weights representing the quantity of nutrients or energy being transferred.
