"WebIn the case of optimal foraging, a type of optimality model known as a marginal value theorem is usually applied. As per this theorem, an organism should decide the economically favorable time to leave a patch while in search of food. The animal goes through the law of diminishing returns in a patch, as with time, it gets harder to find the prey. " - Optimal foraging the marginal value theorem
