9.02 Many biogeochemical processes move matter between reservoirs in Earth's atmosphere, hydrosphere, biosphere, and geosphere. Describe ONE possible pathway a carbon atom might take through the carbon cycle: identify the processes, reservoirs, forms (compounds/organisms) the carbon would be in along the way and whether each part of the journey is part of the "long-term" or "short-term" cycle. Identify TWO ways human activities have altered the carbon cycle and how these actions impact Earth's systems.
