keystone species - arctic fox
The Arctic fox has few relationships towards other animals native to its habitat. They are scavengers most of their lives, picking up other animals leftover, thus making it hard to be the predator in their environment. They are sometimes killed by polar bears, so at times, different sides of the relationship benefit. Without the prey they consume, Arctic Foxes must find another organism to feed on. They feed on lemmings, voles, and other critters, which could be considered a symbiotic relationship, although the prey does not benefit from its side of the bargain.Polar bears, wolves, kittiwakes, and snowy owls are all predators of the Arctic fox, making it the supplier of food for those five main animals.
