is a polar bear a predator or prey
Apex predator Because apex predators have powerful effects on other predators, on herbivores, and on plants, they can be important in nature conservation.[21] Humans have hunted many apex predators close to extinction, but in some parts of the world these predators are now returning.[22] They are increasingly threatened by climate change. For example, the polar bear requires extensive areas of sea ice to hunt its prey, typically seals, but climate change is shrinking the sea ice of the Arctic, forcing polar bears to fast on land for increasingly long periods.[23]
