Which biome is described as extremely cold and dry, known for its permafrost, mosses, lichens, caribou, and snowy owl?

The tundra biome is characterized by its extremely cold temperatures and low levels of precipitation, making it one of the driest biomes. Its defining feature is permafrost, which is permanently frozen subsoil that significantly influences the types of vegetation and animals that can thrive there. In the tundra, you will commonly find hardy plants like mosses and lichens, which have adapted to the harsh climate conditions.

Animal life in this biome includes species such as caribou, which migrate in search of food, and snowy owls, which are well adapted to the cold environment. The conditions in the tundra support a unique ecosystem that has evolved to cope with extreme cold and limited nutrients, making it distinct from other biomes like the savannah, taiga, or temperate forest, which have different climatic and ecological characteristics.
