According to optimal foraging theory..
organisms will have a tendency to select the smallest prey available if they are common, rather than exert more energy in capturing larger prey.
predators will always maximize their rate of energy gain when they forage for more than 1 prey type.
an organism can gain unlimited resources if it invests more energy into increasing its food intake.
a predator will include prey with high handling times in their diet as long as their energy of rate intake increases.
Optimal foraging theory can make predictions about an animal’s food choice. Which of the following is the most accurate statement about optimal diet breadth as resource quality, handling time and distribution changes?
As handling time increases, animals should specialize
As the distance between resources increases, animals should generalize
As the energy content of the resources increases, animals should generalize
As the distance between patches increases, animals should stay longer in a patch
The following diagrams show four distribution patterns of resources. 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. (Shown in image)
You are studying the diet of American bison. You gather the data in the graph below on the effort
bison invest (gray bars, left hand Y-axis) in obtaining different types of grass (X-axis) and the energy
content in calories of the grasses (white bars, right hand Y-axis). According to these data, which type
of grass would optimal foraging theory predict bison choose?

[ Select ]arrow_forwardexplain this: Goal 2: Zero Hunger. The number of undernourished people has dropped by almost half in the past two decades because of rapid economic growth and increased agricultural productivity. Unfortunately, extreme hunger and malnutrition remain a huge barrier to development in many countries. There are 821 million people estimated to be chronically undernourished as of 2017, often as a direct consequence of environmental degradation, drought and biodiversity loss. Over 90 million children under five are dangerously underweight. The SDG’s aim to end all forms of hunger and malnutrition by 2030, making sure all people-especially children-have sufficient and nutritious food all year. This involves promoting sustainable agricultural, supporting small-scale farmers and equal access to land, technology and markets.arrow_forward
