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.
As a result, wetlands are very good carbon sinks (meaning they store a lot of carbon). In summary, coastal wetlands are particularly good at storing carbon because the plants annually sequester (capture) a lot of carbon and then these ecosystems store carbon for long periods of time in their soils.
