Question

Quizplus · Accepted Answer

Deer mice are endothermic animals and require a high metabolic rate to maintain their body temperature, which accounts for a greater proportion of their energetic budget. On the other hand, penguins are adapted to cold climates, and their energy budget is devoted more to deal with cold weather, including keeping their feathers clean, warm, and waterproof.
