Food chains, also called food webs, food networks and/or trophic networks, describe 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.

"Two servings of shrimp scampi per year is absolutely essential, and it is preferable that one be a microwaveable meal from the Contessa frozen-foods line, and the other be eaten at a fancy restaurant, like the Lobster Tail off Route 22, on a nice summer evening with the woman you love," acting Agriculture Secretary Chuck Conner said.
