The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
Ringed seals are both predators and prey. A predator to zooplankton and fish, the ringed seal is considered a primary consumer as well as a secondary consumer. But the tertiary consumer, or top predator, in the Arctic is the polar bear, feeding mostly on seals, including the ringed seal.
Pinnipeds are also preyed on by terrestrial and pagophilic predators. The polar bear is a major predator of Arctic seals and walruses, particularly pups. Bears may seek out seals, or simply wait for them to come by. Other terrestrial predators include cougars, brown hyenas and various species of canids, which mostly target the young. [103]

The 1958 Statehood Act set up a program for polar bear management, and further conservation efforts, including the 1972 Marine Mammal Protection Act, have limited polar bear hunts. [10] Polar bear populations may be threatened by oil development and global warming. [10] [11] Only about 4700 polar bears are known to inhabit Alaska. [12]
The polar bear is the apex predator within its range. [79] Several animal species, particularly Arctic foxes (Vulpes lagopus) and glaucous gulls (Larus hyperboreus), routinely scavenge polar bear kills. [80]
Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves. Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
