Detailed explanation-1: -Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate.

Detailed explanation-2: -The Alpine Tundra While temperature and rainfall usually determine the other biomes, this one is defined mostly by elevation. This elevation causes extreme conditions, which create a unique tundra environment where only the hardiest plants and animals can survive.

Detailed explanation-3: -Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Much of Alaska and about half of Canada are in the tundra biome.

Detailed explanation-4: -(The word “tundra” derives from the Finnish word tunturia, meaning barren or treeless hill.) Instead, the tundra has patchy, low-to-ground vegetation consisting of small shrubs, grasses, mosses, sedges, and lichens, all of which are better adapted to withstand tundra conditions.
