Hibernation primarily helps animals survive by significantly reducing the energy required for survival. During hibernation, animals enter a state of reduced metabolic activity, allowing them to conserve energy during periods when food is scarce and environmental conditions are harsh, such as winter.
While hibernation does not directly make access to food easier or increase the chances of meeting a mate, it does help animals survive until conditions improve, at which point they can resume normal activities like foraging for food and seeking mates. Additionally, while hibernation does not directly protect animal young from predators, it does ensure that the adult animals survive to care for their young when conditions are favorable.
In summary, the primary benefit of hibernation is the conservation of energy during tough times.
