Detailed explanation-1: -Hibernating is a behavioral adaptation that allows the bear to snooze through the harshest part of the year when the temperatures are low and food is hard to find. Hibernating lowers the grizzly bear’s body temperature, heart rate, and need for energy.
Detailed explanation-2: -When the time is right, these bears enter a den and do not eat; their heart rate and body temperature decreases to allow the bear to conserve energy.
Detailed explanation-3: -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.
Detailed explanation-4: -Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months.
