Abiotic for desert: Sand
Biotic for polar: Polar bears
Biotic for desert: Cacti

If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.
