Answer:
Polar bears do not actually hibernate like some other mammals do. Instead, they experience a similar physiological response called "walking hibernation" or "winter dormancy." During the winter months, when food sources are scarce and hunting becomes difficult, polar bears reduce their activity levels to conserve energy. They may enter a state where they remain relatively inactive, although they are still capable of waking up and moving around if necessary. This adaptation helps them survive the harsh Arctic winters when seals, their primary prey, are less accessible due to frozen waters.
