Question
Chapter 36.3, Problem 2MC
Summary Introduction
To describe:
In what way the optimal foraging theory explains an animal’s foraging decisions.
Concept introduction:
The optimal foraging theory states that natural selection favors those species whose behavioral strategies maximizes the amount of energy collected per unit time while foraging for food.

Students have asked these similar questions
As described by the Optimal Foraging Theory, and animals feeding behavior should maximize ________ and minimize ________. (Fill in the blanks)
Group of answer choices
energy obtained, social interactions
energy expended, energy obtained
energy obtained, energy expended
social interactions, energy obtained
interpret the following graph:
In the graph, the number of days are 18.. 1 day is equal to 60 sec. days are taken on x-axis. The mean foraging times are taken on y-axis.
Optimal foraging theory suggest that a predator selects among possible prey based on their relative profitability (energy gained per unit of energy expended). Do you think that predator directly evaluate the profitability of potential prey items before selecting or rejecting them ? If not, how mighta foraging strategy evolve ?

Each circle represents one unit of a resource, say, a food item. For which of these distributions would the Marginal Value Theorem be useful for making predictions about optimal foraging behavior.
