Tundra vegetation refers to the type of natural vegetation that is found in regions with extremely cold climates, such as the Arctic and alpine regions. The tundra is characterized by low-growing plants, such as mosses, lichens, grasses, and small shrubs. These plants have adapted to survive in harsh conditions, including freezing temperatures, permafrost (permanently frozen ground), and a short growing season.

Option 1, Temperature deciduous, refers to the type of natural vegetation that is found in regions with moderate climates and distinct seasons. This vegetation is characterized by trees that lose their leaves in the winter, such as oak, maple, and beech trees.
