Which biome is characterized by very low temperatures and limited vegetation?

The tundra biome is characterized by very low temperatures, a short growing season, and limited vegetation due to its harsh climate. This biome is often found in the polar regions and at high altitudes, where the conditions are too extreme for most plants to thrive. The soil, known as permafrost, is permanently frozen below the surface, which further restricts the growth of deep-rooted plants.

In tundra regions, vegetation is typically sparse and consists mainly of low-growing plants such as mosses, lichens, and small shrubs that are adapted to the cold environment. The low temperatures limit the rate of decomposition, leading to a build-up of organic matter that becomes trapped in the frozen soil.

This unique combination of factors makes the tundra distinctly different from other biomes. For example, tropical rainforests are known for their high temperatures and abundant rainfall, supporting a rich diversity of flora and fauna. Grasslands, on the other hand, feature moderate temperatures and are dominated by grasses, while deserts possess low rainfall and can have either hot or cold conditions but still support a different kind of vegetation.
