Explain body size contribute to the survival of mammals in cold habitats

• Mammals in cold habitats usually have a large body size as a result of extra fat deposits under the skin.
• The big size reduces the surface area to volume ratio and therefore reduces the rate of heat loss from their bodies across the surfaces.
• The fat deposits under the skin insulates and prevents heat loss to the environment.
