F). Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower. During the summer, temperatures rise somewhat, and the top layer of seasonally-frozen soil melts, leaving the ground very soggy. "Great Plain of the Koukdjuak".

There are hot deserts, but there are also cold deserts that have snow in winters, making it difficult for plants to grow. This biome also has extremes of temperature on both sides. A biome is made of several ecosystems. They are brightly colored and move fast. Please spread the word. 5 There are also a few fish species.
