What challenges do Arctic foxes face in cold weather?

Arctic foxes face several challenges in cold weather, including extreme temperatures that can lead to hypothermia and frostbite. Their food sources, such as lemmings and other small mammals, may become scarce due to heavy snowfall or freezing conditions. Additionally, the increasing impact of climate change is altering their habitat and prey availability, making survival more difficult. Adaptations like their thick fur and burrowing behavior help them cope, but these challenges can still threaten their populations.
