Explanation:

Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).

Therefore an elephant has a lower surface area to volume ratio than a mouse.

The smaller an object is the greater its surface area to volume ratio.

Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.
