Will Orcas Overtake Polar Bears as the Dominant Species in the Arctic? Will Orcas Begin Hunting Polar Bears?

Nature is inherently about the survival of the fittest, with weaker animals facing the risk of being hunted. The relationship between polar bears and orcas is a good example, where polar bears hunt orcas, but polar bears themselves also have opponents.

Polar bears and killer whales are both powerful predators. Polar bears are practically the top predator in the Arctic, but why are killer whales targeting them?

When killer whales encounter polar bears in the Arctic, they will definitely conflict because of food. A comparison will show that the polar bear is clearly at a disadvantage. Killer whales are massive, with weights reaching about 10 tons. It's hard to imagine that clumsy polar bears can compete with such a large animal. Moreover, polar bears are only 10 times lighter than killer whales, which is a huge disparity. Therefore, the polar bear's fate is to be preyed upon.

However, the chance of polar bears and killer whales meeting in the Arctic is very low, and killer whales won't target polar bears if they have enough food. As long as the polar bear doesn't provoke them, there will be no conflict. I don't think polar bears will intentionally provoke something so much stronger than themselves.
