Carbon Dioxide Cycle
Carbon dioxide is the most important things on earth. It provides people with air that keeps them going. the tundra is a carbon-dioxide hole meaning it takes in more carbon dioxide than it lets off, which is not the best thing. Plants absorb oxygen, sunlight and water in photosynthesis during the summer, but freeze quickly when winter arrives. This cycle means that it traps carbon dioxide in the permafrost, where it is stored. In the tundra the carbon cycle plays a big role. One different thing about it is the temperature. The cold slows the decomposition in the soil. Carbon is broken down more slowly and stored in the soil over long periods of time. Today there is twice as much carbon in the ground than there is in the atmospher.
