Identify each adaptation as structural or behavioral adaptations.
1.Monkeys have a prehensile tail that allows them to grab and hold onto tree branches.
2.Moose make mating calls to locate potential mates.
3.Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters.
4.Humans have five toes on each foot to help them maintain balance.
5.Many birds migrate south for the winter in search of food.

Structural adaptations are physical changes. Option 1, 3 and 4 is the example of structural adaptation while option 2 and 5 are the examples of the behavioral adaptation.

Structural Adaptation:

These are the physical features that organism adapted during evolution to increase the chances of survival.

Example:

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches.
Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters.
Humans have five toes on each foot to help them maintain balance.

Behavioral Adaptation:

These are the behaviors that organisms have adapted during the evolution to increase the chances of survival.

Example:

Moose make mating calls to locate potential mates.
Many birds migrate south for the winter in search of food.

Hence, We can conclude that Option 1, 3 and 4 is the example of structural adaptation while option 2 and 5 are the examples of the behavioral adaptation.
