Summary Introduction
Introduction:
Foraging is the process of movement of animals for the process of finding of food from one place to another. Every organism needs food and water for its proper growth and its survival. There is a theory called the optimal foraging theory. This theory basically tells that the reason why an animal sticks to have only few types of foods only.

Beavers are nocturnal and therefore, eat mainly during the night. Beavers normally eat the bark of trees, leaves, twigs, lily roots and the buds of deciduous trees. How do the claws of the beaver help it to compete for its food?
A) The beaver's claws help it to dig holes to search for animals hiding underground.
B) The beaver's claws help it to hide its face when predators are near.
C) The beaver's claws help it to feel for food in the grass in the darkness of the night.
D) The beaver's claws help it to climb high into trees to obtain its food.
According to optimal foraging theory
a. individuals minimize energy intake per unit of time.
b. energy content of a food item is the only determinant of a forager’s food choice.
c. time taken to capture a food item is the only determinant of a forager’s food choice.
d. a higher energy item might be less valuable than a lower energy item if it takes too much time to capture the larger item.
In the Amazon forest you discover a very brightly colored caterpillar. The local people tell you it is good to eat but fairly rare. You try it and it is delicious. What would you expect to find in the same area?
Group of answer choices
a. lots of other caterpillars that taste even better
b. a restaurant that makes caterpillar tacos
c. another animal that protects the caterpillars
d. a very similar species that is toxic

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.
