WebFood: Optimal Foraging Models. Page 1 Page 2. Theories of optimality involve a mathematical model of cost and benefit analysis that can give quantitative predictions about an animal's behavior. These hypotheses can be tested experimentally or through comparative phylogeny.

By assuming that animal activities are optimized to maximize the rate of net energy gain, optimal foraging theories provide testable hypotheses as well as bases for interpreting complex animal behaviour [ 3, 4 ].
WebOptimal foraging theory uses predators as the object of analysis. There are four functional classes of predators: True predators attack large numbers of their prey throughout their life. They kill their prey immediately, or shortly after the attack. They may eat all …
