WebForaging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a ... WebForaging behavior is a series of actions that predators take to hunt for food and it includes searching, chasing, catching, processing, and ingesting. It is an excellent indicator for evaluating individual performance as marine organisms need food to supply vital energy for basic life functions.
