Step-by-step explanation:
One adaptation you would expect to find in an animal in the taiga biome but not in the alpine is hibernation. Hibernation is a state in which an animal's body processes slow down and its body temperature falls, allowing it to conserve energy during the winter months when food is scarce. Many animals in the taiga, such as ground squirrels and bears, hibernate to survive the cold temperatures and lack of food.
