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.
Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
Coastal wetland ecosystems (salt marshes, mangroves, and seagrass beds) can store large quantities carbon for two main reasons: 1  Their plants usually grow a lot each year, and in the process, capture (or sequester) large amounts of carbon dioxide (CO2).
