The primary food for a polar bear is seals, particularly ringed and bearded seals. Polar bears are apex predators in the Arctic and rely on a high-fat diet to sustain their body temperature and energy levels in extremely cold environments. They typically hunt seals by waiting near breathing holes or breaking through sea ice. The fat and blubber of seals provide the necessary calories and nutrients that polar bears need for survival. As climate change impacts sea ice habitats, polar bears are facing challenges in accessing their primary food source, which threatens their survival and population health in the Arctic ecosystem.
