What biome has animals such as polar bears arctic foxes and mountain goats?

The biome that houses polar bears, arctic foxes, and mountain goats is the tundra.

Here's why:

* Polar bears: These iconic animals are adapted to the harsh, icy conditions of the Arctic tundra.

* Arctic foxes: These small, agile foxes also thrive in the tundra's cold climate.

* Mountain goats: While found in mountainous regions, mountain goats are particularly adapted to the alpine tundra, which is characterized by high elevation and cold temperatures.

While other biomes may have some overlap with the tundra, these specific animals are most commonly found in the tundra due to their specific adaptations.
