They are usually in the middle somewhere below its predators the polar bear and eagle. But they are not at the bottom. The lemmings or Arctic Hare are...usually.
Did you know that they have thick fur on their feet?
He is most likely to be in the middle because of it being a OMNIVORE not a CARNIVORE...he would be below its predators, the golden eagle and polar bear...
Since he is a carnivore ,he;s near the top
The arctic fox is a consumer, so it would be at the top!!!
