Polar bears who have white fur and live in the Arctic must use camouflage adaptation.
Step-by-step explanation:
The white furs of polar bear is there so that they camouflage the snowy environment of arctic.
The white fur is confused with snow by predators. Also, the thick fat layer is for insulation and keeping itself warm in cold habitat. These features of polar bear are an example of natural habitat adaptation.
Apart from this they have greasy body surface that does not sustain water to their body and the wide feet are for better grip to walk on ice.
Polar bears have evolved from the brown bears and got geographically separated and modified itself to arctic region climate.
The blending with the environment caused polar bears best adapted for the environment and hence evolution.
