Detailed explanation-1: -hibernation. noun. state of reduced physiological activity, similar to sleep, in which some animals spend the winter. metabolism.

Detailed explanation-2: -Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism. Research into the processes involved in hibernation could result in medical benefits for people.

Detailed explanation-3: -For hibernating animals, an early wake-up call isn’t just an inconvenience-it can be downright lethal. Waking up from hibernation requires a lot of energy, depleting reserves that are key to surviving the winter. It’s not just bears that are in danger if they wake up from hibernation at the wrong time.

Detailed explanation-4: -Do animals ever wake up during hibernation? Though the physiological changes are profound, usually no animal in hibernation remains completely torpid for more than about 30 days at most, which is the case for hazel dormice and fat dormice.

Detailed explanation-5: -A) Bears hibernate during winter, but aren’t sleeping the whole time. Hibernation for bears simply means they don’t need to eat or drink, and rarely urinate or defecate (or not at all). There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available.
