Not much. Contrary from all the other bear species, the polar bear is almost entirely carnivorous. Mostly out of necessity, not much grows in the high arctic and nothing grows on the polar ice cap, which is where the polar bears live.
No.
use it for food needs
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 their teeth, claws and strength in their paws and jaws.
polar bears reproduce sexually which mostly uses egg and sperm equals a baby
to be warm
All Polar Bears are left handed.
because sun bears are so use to being warm all year and polar bears can adapt better ( i reALLY DONT NO ?)
polar bears can be protected by killing them all and then using the meat to feed the dogs and use the skin as a condom
The diet depends on the habitat e.g. the polar bear will hunt and consume animals below it in the polar habitat e.g. seals, whereas the brown bear which resides in woodland habitats would feed on woodland creatures e.g. foxes.
Scientists once thought that polar bears were left handed. Now they believe that they have no preference and use both paws equally.
Fear is a debatable term to use for any carnivore, but when the two species have come into contact around food sources, the polar bears do usually give way to the brown bear.
