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.
Although the oceans are currently the greatest carbon sink, terrestrial carbon sinks are also important. The greatest. terrestrial carbon sinks occur in young, growing forests, because a hectare of trees holds up to 50 times more carbon. than a hectare of grasses or crops.
