WebJun 20, 2024 · Applying optimal foraging theory requires researchers to consider how a predator chooses, searches, handles and consumes their prey. Choosing prey Predators should ignore low profitability prey items when more profitable items are present and abundant. This is a prediction of the ‘optimal diet model’. WebAccording to much current theory, organisms should be able to balance the conflicting demands of the need to feed efficiently and the need to avoid predators while feeding. WebAs a result, foraging strategies can actually drive our behavior in a myriad of ways. Optimal Foraging Theory can be demonstrated as the following: Figure 12.1: The Marginal Value Theorem shown graphically.
