If the temperature falls too low some animals will awaken slightly and shiver to warm up a bit. ![]() Some hibernators go into such a deep sleep that it is almost impossible to wake them, and they appear to be dead. Can you name some of the animals that hibernate in the winter? Some insects also hibernate and to keep warm they find holes in the ground, under tree bark or in rotting logs. When the weather gets cold, they move down to the bottom of lakes and ponds and some even burrow into the mud. They shelter under logs, rocks and fallen leaves in the water. Some of the hibernating animals include fish, frogs and turtles, which have no way to keep warm during winter. It sends a quick burst of energy to warm these organs first when it is time to wake up. The brown fat forms patches near the animal’s brain, heart and lungs. Fat will break down over a of time than carbohydrates and alow the animal to. For Yellowstone area bears, it’s more like four or five months. The time frame varies, with bears in northern Alaska hiding away in their dens for up to seven months. While not all bears hibernate, the majority do. Kind of Molecule Energy Released in Body calories/grams) Protein Fat Carbohydrate Animals that hibernate in the winter require more fats in their diets.

There are two types of fat – regular white fat and brown fat. a) Macromolecules contain varying amounts of energy, as shown in the table below. Hibernating animals get ready for their winter sleep by eating extra food and storing it as body fat which they then use as energy while sleeping. Hibernation is a deep sleep that helps them to save energy and survive the winter without eating much.ĭuring hibernation the animal’s body temperature drops, and its heartbeat and its breathing slow down so that it does not use much energy. Some animals solve this problem by hibernating. ![]() For most animals finding enough food in winter can be difficult when the main source of food like insects or green plants is in short supply. ![]()
