Sore throat is a symptom, not a disease. In each case, there was a different cause that dictated a different treatment. The scratchy throat probably was a mechanical problem caused by dry, heated winter air and aggravated by my friend's tendency to breathe through her mouth when she sleeps.
Biogeochemistry includes the history of the great carbon reservoirs in the crust of the Earth, like limestone rocks and the coal deposits, as well as the distribution of nitrate and phosphate in the ocean.
Major reservoirs (in order from greatest to least): sedimentary rock is the largest, ocean, soil, atmosphere, organisms. Fluxes: Rate at which carbon flows from one reservoir to another.-Photosynthesis (CO2 from atmosphere transferred to plants)-Plant respiration (CO2 from plant to atmosphere)
