What other organisms does the Arctic fox rely on to survive?

The Arctic fox primarily relies on small mammals, particularly lemmings, as a key food source for survival. Additionally, it scavenges on the remains of larger animals, such as seals, that are left behind by polar bears. The fox may also consume birds, berries, and fish when available, showcasing its adaptability to the harsh Arctic environment. This diverse diet helps it thrive in a region with limited resources.
