to be warm
if you are asking how does it keep warm polar bears have a layer of fat which they use for insulation also there fur is pretty thick
yes they use it to keep warm.
Polar bears require huge amounts of energy to maintain their body temperature in the cold, and they must build up fat reserves to do that. Seal blubber is optimal food source for them because their blubber is so rich in calories and fat.
For Arctic tribes, the polar bear was used not only for meat, but their fur was used for clothing and footwear, their fat was used for fuel, sinews used for sewing, etc. Today, polar bears are protected and are frequently used as a symbol for conservation and global warming.
No.
If polar bears didn't have claws they would be vulnerable to attack from other animals because Polar bears can use their claws to defend themselves. Polar bears can also hunt and find food using their claws therefore Polar bears need their claws to survive!.
Polar Bears use a combination of fur and blubber (or fat) to keep themselves warm. Both the blubber and the fur trap heat as well as keeping out water and chilly winds.
use it for food needs
Polar bears use their teeth, claws and strength in their paws and jaws.
polar bears reproduce sexually which mostly uses egg and sperm equals a baby

All Polar Bears are left handed.
