A

Luring behavior is an adaptive foraging strategy in animals when the benefits of locating the prey outweigh the costs of being detected by prey.

TRUE

The marginal value theorem predicts that an animal should leave a feeding patch when its rate of food intake in that patch drops below the average rate for the habitat.

TRUE

Match each hormone with the behavior it most commonly regulates:

A. It would freeze. B. It would be confused by the information and not know which way to fly. C. It would continue flying straight ahead in an attempt to avoid the bat. D. It would fly in a downward trajectory in an attempt to avoid the bat.

C

Which of the following is NOT a standard component of an optimal foraging model? A. time spent procuring food B. time spent locating food C. time spent fighting for food D. energy/calories gained from feeding

C

A hypothetical species of sloth would be favored by selection to be a seasonal generalist forager on leaves during spring and summer if the leaves are predictably available, abundant, and of high nutritional quality.

False

False
