Secondary Consumer

Secondary Consumers are carnivores that feed on herbivores. Polar Bears are the world's largest land animal. They can be found in the Arctic, Canada, Russia, United States, Norway, and Greenland. These countries have banned killing polar bears, because they are almost going extinct. Ice is melting because of global warming, also there are going extinct since they are top of the food chain. Since they are on the top of the food chain the toxin accumulates into their body. They like eating seals but they eat other animals, too.

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.
