Detailed explanation-1: -tundra, a major zone of treeless level or rolling ground found in cold regions, mostly north of the Arctic Circle (Arctic tundra) or above the timberline on high mountains (alpine tundra ).

Detailed explanation-2: -Arctic-alpine tundra vegetation similar to the Arctic Tundra occurs at elevations above treeline. Many plant species are the same as found in the Arctic, although the mountain flora may be richer in species.

Detailed explanation-3: -Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool.

Detailed explanation-4: -Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Detailed explanation-5: -Arctic tundra is a very cold, windy, and treeless biome that’s snow-covered for much of the year. It’s found in the northern hemisphere, encircling the north pole and extending south across parts of Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, to the coniferous forests of the taiga.
