Decomposer

A decomposer is an organism that breaks down dead animals into nutrients for plants. Arctic moss or Calliergon giganteum grows in the harsh terrain of hundred mile winds and -25 degrees Celsius. Since there is only eight weeks of summer photosynthesis does not really work. Since there is only thirty centimeters of rain a year the tundra is unusually dry. The tundra is about 75% covered in permafrost. There are many cracks because of the freezing and thawing. The frozen soil prevents water from sinking in the ground. This causes many akes, streams, and bogs. The most unique thing is that it grows in freshwater Arctic lakes and fens(wetlands). It is an aquatic plant and grows in the bottom of lake beds.
