• Animals respond to cold winter weather in different ways.
• Some animals find food or eat food they have hidden.

• During hibernation, normal body activities slow down. The heart beats slowly, and breathing almost stops.
• A hibernating animal doesn’t use much energy, because the body is barely working.
• There is enough fat stored in the animal’s body to keep it alive through the winter.
