What is the Arctic Tundra Biome?

Tundra lies between 55 ° and 70 ° to the north, with the coldest, driest and most brutal conditions for life on Earth. The youngest biom, created only 10,000 years ago, is blewing over a flat, immediate landscape. Tundra is taken from the Finnish word tunturia, which means "infertile soil". Parts of Greenland, Northern Canada and Polar Cap belong to the Arctic Tundra. The active layer of permafrost could partially thaw for several months during the slight summer, but the inactive layer is permanently frozen. If low precipitation and small sunlight were not enough to discourage vegetation, permafrost prevents the roots of plants from reaching far below the ground. The soil has certain nutrients with organic matter contributing nitrogen and rain producing phosphorus. During the short -lived two -month growing season moss, lichens, liver and several flowering plants with Shpovolite root systems can grow. They survive on only 6-10 inches (15-25 cm) rain per year. Giant mammals as well as Musk Ox and Ice MEDelves, emitted to a living due to specialized adaptations. Their coats are strong and waterproof; Their smell acute. Arctic fox does not even have to hibernate, as it will withstand very low temperatures. Shrews and Hares Scamper from the lair to provide food for a snowy owl.

Surprisingly, Tundra has a rare ecology that makes the "carbon sink". This means that Tundra removes carbon dioxide from the atmosphere because it absorbs more gas than it creates. The absence of a lot of biomass means that there is little organic disintegration. Reducing the amount of carbon dioxide helps fight the growing threat of global warming, which has already been damaged by the melting of glaciers.
