Which biome, which can be either hot or cold, is primarily defined by receiving less than 25 centimeters (10 inches) of precipitation per year?

Desert

Deserts are defined by their extreme dryness rather than their temperature, meaning they can be scorching hot or freezing cold. Surprisingly, the largest desert on Earth is Antarctica, which receives very little precipitation despite being covered in ice. This lack of water forces desert life to develop unique survival adaptations, such as deep root systems or water-storing tissues.
