8. For each of the biogeochemical cycles in the table below, list at least three areas on Earth where the chemical elements or compounds are stored (i.e., reservoirs). Biogeochemical cycles Storage pools or reservoirs Water Carbon Nitrogen Phosphorus 9. For the three biogeochemical cycles listed below, choose two reservoirs you have listed in the table from Question #8 and describe how the chemical elements/compounds moves between the two reservoirs. Note, you do not have to describe the complete cycle for each element/compound, simply describe the processes that connect two of the reservoirs that make up the cycle. Water: Carbon: Nitrogen:
