Problem Overview:
The task is to classify each animal adaptation as either
structural or
behavioral.
-
Structural adaptations are physical features of an animal that help it survive in its environment.
-
Behavioral adaptations are actions or behaviors that animals perform to survive in their environment.
Solution:
Let's analyze each adaptation one by one:
