In three scentences explain what biome compromises most of antartica and why the continent is described as being part of tbis biome.

Antarctica is predominantly comprised of the frozen desert biome, characterized by extremely low temperatures and little precipitation. This biome is found on the continent of Antarctica because it experiences long, harsh winters and short, cool summers, making it difficult for plant life to thrive. Additionally, the majority of Antarctica is covered in ice and snow, further contributing to its classification as a frozen desert biome.
