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.
A carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorb.Forests, soils, oceans and the atmosphere all store carbon and this carbon moves between them in a continuous cycle.This constant movement of carbon means that forests act as sources or sinks at different times. Not all stores of carbon are naturally cursed with such fluctuations however.In the context of climate change, the most important carbon stores are fossil fuel deposits as they have the unique benefit of being buried deep inside the earth, naturally separated from the carbon cycling in the atmosphere.ecause of this increase in atmospheric carbon, a lot of emphasis and hope has been put into the ability of trees, other plants and the soil to temporarily sink the carbon that fossil fuel burning releases into the atmosphere.
