Answer:
Animals respond to Environmental stimulus if they hibernate.
Explanation:
A stimulus is any change in the environment that affects the activity of an organism or what causes an animal to act in a certain way.
Hibernation is an innate behavior. It is a resting state that helps animals survive the winter.
During hibernation a warm-blooded animal like a ground squirrel slows down its heart rate and breathing rate.
Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship.
