What are typical adaptations for cold climates?
White fur for camouflage, big feet to distribute body weight, thick fur reduces air movement. Prevents heat loss through convection. Traps a layer of warm air. Body fat (Adipose tissue in humans)

What are adaptations in hot climates?
Camouflage. Less fat. Big ears means small SA:V ratio. Thin fur. Bushy tail for extra warmth. Again, small paws and long legs for small SA:V ratio.

What is distribution?
How the species is spread out.
11 of 15

Water, light, nutrients and for animals: mates, food, and predators.
