I don’t believe use as humans give too much thought about how taking down a tree, using limestone and using fertilizers can upset the natures balance. In the carbon cycle there are two processes which are photosynthesis and metabolism. Photosynthesis is the process of plants using carbon dioxide and creating oxygen in which humans need to live. Metabolism is the process of changing chemical energy into another form like heat and other forms of energy. Humans have impacted this cycle by burning of fossil fuels coal, etc. What happens is when humans burns fuels it release carbon dioxide into the air along with water molecules. When the extra carbon dioxide is releases into the environment how does it disperse? With the additional carbon dioxide in the atmosphere scientist believe this is causing the greenhouse effect. The greenhouse effect means the changes in the global climate and the changes in sea levels. The phosphorus cycle is the movement of phosphorus through the biosphere, hydrosphere, and the lithosphere. Phosphorus is entered through the environment by rocks or by bird dropping called guano.
