How does having a small surface area to volume ratio minimize heat loss in polar bears?

Answer 1

Heat is produced in the body and becomes lost through the surface.So increasing the volume of the body means more heat is produced in the cell, and decreasing the surface area means less heat is lost.

Polar bears' small ears, tail, and compact body shape reduce the surface area through which heat can escape, helping them retain body heat in cold environments. They also have a thick layer of insulating fat under their skin, which reduces heat loss.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
