Antarctica is the continent primarily made up of tundra ecosystems, characterized by its cold climate and sparse vegetation. Tundra regions typically feature low-growing plants, mosses, and lichens adapted to harsh conditions. Antarctica's tundra is mainly found in coastal areas, where the ice eventually gives way to vegetation during the brief summer months. This unique environment is crucial for various animal species, including penguins and seals, which thrive in the cold. The delicate balance of this ecosystem makes it a focus for climate change research.
