Tundra Biome Facts

Tundra Biome Facts
The tundra biome is an ecosystem situated near the North Pole in the Arctic Circle. It is by far the coldest of all biomes. The winters are extremely cold with temperatures typically below -34° C. The summers last only about two months and the temperatures are still very cold ranging from 3° to 12° C. This biome still sustains life although it encounters these extreme temperatures. Some animals, insects, and even plants thrive there.
