How might an organism that relies on the

environment to maintain body temperature do so?

Answer: some animals need certain weather such as polar bears stay in the cold and snow, while camals stay in the dessert in the heat and be just fine, animals adapt to their surroundings

This is because in warm-blooded animals, the heat they lose is proportional to the surface area of their bodies, while the heat they produce is proportional to their mass. This means that larger warm-blooded animals can generate more heat than they lose and they can keep their body temperatures stable more easily.
