Snapshot 1: production of green turtles

Snapshot 2: production of reef sharks

Snapshot 3: production of tiger sharks with maximum efficiency and varied consumption values

The equation used is , where is production, is efficiency, and is consumption, with production and consumption expressed in . Production is equal to the product of ecological efficiency—how efficient the organism is at using food—and consumption. The production of an organism measures how much of the food intake contributes to its growth.
