AP BIOLOGY

Detailed explanation-1: -It sends a quick burst of energy to warm these organs first when it is time to wake up. If the temperature falls too low, some animals will awaken slightly and shiver to warm up a bit. Hibernators may also wake up for a short period every few weeks to go to the toilet and eat a little food if it is available.

Detailed explanation-2: -In the spring, though, all animals that hibernate leave their deep sleeps for good. They start to take advantage of the more abundant food supply and comfortable conditions that spring offers. Spring also welcomes new baby animals to the forest floor, such as deer and coyotes.

Detailed explanation-3: -Hibernation differs from daily torpor in that it usually involves much lower body temperatures and metabolic rates, and is often seasonal. In addition, while animals who go into daily torpor wake up and forage or feed in the usual way, hibernating animals either feed off their body fat or on specially stored food.

Detailed explanation-4: -During hibernation, the animal’s body doesn’t need nearly as much energy to stay alive. The body gets all the nutrients it needs to maintain itself by burning the animal’s stored body fat. The body also burns fat to warm the animal whenever their temperature gets too low, which prevents freezing.

Detailed explanation-5: -True hibernating animals sleep so deeply that waking is difficult and takes a lot of time and energy, she said. These animals may wake every few weeks to eat and, like in the case of groundhogs, use the bathroom in their burrow. As spring inches closer, they wake more frequently.
