Question

Polar bears are predators that live in the Arctic. Why would a polar bear that is born with naturally darker fur be less likely to survive than one with white fur?

A The darker fur would cause to polar bear to overheat in summer months as dark fur retains heat more than light fur.

B It would be mistaken for a different animal and hunted by other polar bears.

C It is more easily seen by predators, or it may be more easily seen by its prey and so cannot catch enough food.

D Darker fur is more dense than lighter fur, when wet, the darker fur would be a disadvantage to the polar bear as it would not be able to swim as efficiently.

Answer 1

Polar bears with naturally darker fur would be less likely to survive in the Arctic due to decreased camouflage capabilities, making it harder for them to hunt seals and avoid detection. This adaptation of white fur is crucial for blending into the Arctic environment.

Step-by-step explanation:

A polar bear born with naturally darker fur would be less likely to survive in the Arctic than one with white fur primarily because of camouflage. The white fur of a polar bear serves to blend in with the snowy and icy environment of the Arctic, which is a crucial adaptation for hunting. Seals, the main prey of polar bears, could more easily spot a dark-furred bear against the white background, making it more difficult for the bear to catch food. This camouflage also helps polar bears avoid detection by potential competitors or threats.

Moreover, white fur does not absorb sunlight as much as darker fur might, which could help the polar bear with thermal regulation, although their thick fur and layer of blubber mostly serve this purpose. The role of fur color in thermal regulation in polar bears is minimal compared to the importance of camouflage for hunting.
