Transcript of Biomes: Arctic Tundra

Arctic Tundra By Hillary Bui Arctic Tundra is mostly found in the northern hemisphere and very rarely is Arctic Tundra found in the southern hemisphere in the islands off the coast of Antarctica Geographic Locations Producers and Consumers Fungi Arctic Fox Lichen Primary Producers Characteristics Primary Consumers Reindeer Secondary Consumers Decomposers A unique characteristic of the arctic tundra is that the ground is permanently frozen, which is called permafrost. Neither plants or water can break through the permafrost. However the layer about the permafrost, or the active layer, thaws each summer. Musk Ox Brown Bear The arctic tundra has only two seasons; summer and winter. There is less than 10 inches of precipitation per year and very dry winds in the tundra, which make a desert like climate. During the summer when the snow melts the water has nowhere to go because of the permafrost so pools of water form on the surface.

Musk Ox A physical adaptation of the Musk Ox is its two layers of fur, which has a short and long layer. The short layer traps in air and warms the air with body heat. The long layer protects the Musk Ox from wind and rain. Another adaptation of the Musk Ox would be its very hard hooves, which help the Musk Ox break ice in the winter to drink water underneath.
