why is the reindeer found in the tundra biome

The reindeer is well-adapted to the harsh tundra climate, with a thick coat of fur to keep it warm and tough hooves to walk on ice and snow. Reindeer are also able to go for long periods of time without food or water, making them well-suited to the tundra's sparse resources. They are also able to dig through snow to find food, using their hooves to uncover lichen and other vegetation. The reindeer is a majestic and resilient animal that has adapted perfectly to life in the tundra.
