Answer:
Energy
Step-by-step explanation:
Hibernation allows an animal to save energy during a time in which there is not a large food source.
This generally occurs to carnivorous as well as omnivores in which their prey is "dead" during the time, or have migrated.
An example of an animal that hibernates during the winter is the Grizzly Bear, who generally eats to full before they hibernate for the winter.
