The primary diet of polar bears consists mainly of seals. They are skilled hunters and primarily rely on sea ice to catch their prey, particularly ringed and bearded seals. This diet is crucial for their survival, as seals provide the necessary fat and nutrients that polar bears need, especially in the harsh Arctic environment. During the summer, when ice is less prevalent, polar bears may struggle to find food, leading to a reliance on alternative sources, such as scavenging or eating smaller marine animals. This dependence on seals makes them an apex predator in their ecosystem, but also highlights the impact of climate change on their habitat.
