Learning Objectives

8.2.1 Explain the theory of optimal foraging by outlining the factors that influence the net benefit of foraging.

8.2.2 Summarize what determines optimal foraging in an area with different food densities with reference to the marginal value theorem.

8.2.3 Describe how the presence of predators can impact foraging behavior.

As we've seen, there are costs and benefits to the behavioral choices that animals make, which can influence the overall benefit of a behavior to animals. In this section, we'll consider the trade-offs faced by animals in their search for food and the potential for behavior to maximize the benefit they receive while foraging.
