Answer:
The carbon cycle, as the name suggests is the system in which carbon moves through the biogeochemical spheres. These include the biosphere, lithosphere, atmosphere, and hydrosphrere. The actions that move carbon through each part are called fluxes. Fluxes in the carbon cycle are balanced, as shown in cellular respiration, photosynthesis, and decomposition. However, human activity has disrupted it, making the production of carbon dioxide to the atmosphere and hydrophere harmful to life.
