Consider the following:

Bats
Bears
Rodents

The phenomenon of hibernation can be observed in which of the above kinds of animals?

Explanation

Hibernation is a state of decreased physiological activity and lowered body temperature that certain animals, such as bats and bears, undergo during the winter months to conserve energy and survive periods of limited food availability.

Statement 1 is correct: Bats, especially those living in temperate regions, often enter a state of hibernation during the colder months when their food sources (insects) are scarce.

Statement 2 is correct: Bears, including the brown bear, black bear, and polar bear, are well-known hibernators.

Statement 3 is correct: Many rodent species, including groundhogs and chipmunks, are true hibernators.

Thus, all three statements are correct.
