Which biome is characterized by extremely cold temperatures and little vegetation?

The tundra biome is characterized by its extremely cold temperatures, especially in the winter, and has very limited vegetation. This environment is typically found in high-latitude regions, such as near the Arctic and Antarctic circles. The cold climate inhibits the growth of trees and larger plants, leading to a landscape dominated by mosses, lichens, and small shrubs. The soil in tundra regions is often frozen, a condition known as permafrost, which further restricts plant growth.

Tropical savannas, by contrast, are warm and characterized by grasslands with scattered trees, while temperate forests have a higher diversity of plants and trees, experiencing moderate temperatures and precipitation. Deserts are known for low precipitation and can be hot or cold, but they do not exhibit the extreme cold temperatures characteristic of the tundra.
