Detailed explanation-1: -Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.

Detailed explanation-2: -Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions.

Detailed explanation-3: -Tundra biome is located in the far north and is characterized by persistent soil ice (permafrost) throughout the growing season which in turn does not allow growth of any vegetation.

Detailed explanation-4: -The tundra biome is characterized by extremely low temperatures, little nutrients, short growing season, low precipitation, and presence of permafrost. Permafrost is a layer of frozen soil and plant matter that is permanently frozen all year round.
