Bears, with their keen intelligence and adaptability, have managed to thrive in a variety of habitats, ranging from dense forests and grasslands to icy tundra and mountainous regions. Their ability to adjust to diverse environments is a testament to their evolutionary success, as they have become apex predators in their respective ecosystems. The polar bear, for instance, has evolved to master the harsh Arctic conditions, relying on its powerful limbs and keen sense of smell to hunt seals on sea ice.
