Final answer:
Alpine biome animals exhibit adaptations like insulating feathers and seasonal color changes to survive in cold environments; large paws assist in movement and large lungs aid in oxygen uptake.
Step-by-step explanation:
The characteristics of animals in the alpine biome include various adaptations that allow them to survive in extreme conditions. Insulating feathers is an example of such an adaptation, as seen in the ptarmigan, whose plumage provides vital insulation against the cold. Another adaptation example is the seasonal color change in the Arctic fox, which helps it blend with its environment to evade predators and hunt more efficiently throughout the seasons. Large paws and large lungs are also adaptations found in alpine animals, assisting in traversing snowy landscapes and maintaining sufficient oxygen uptake in thin mountain air, respectively.
