Round 1: Tossup 2

The capacity to maintain this quantity is considered low for systems with a high Revelle factor. This quantity is plotted on the x-axis of a Bjerrum ("B’YAIR-um") plot. A decrease in this quantity drives the CCD upward, damaging the habitat of coccolithophores (15[1])(“kok-oh-LITH-oh-fohrs”). Aragonite-using organisms (15[2])are the first to be affected (-5[1])by changes in this quantity. (*) Coral bleaching (-5[1])is exacerbated by a global decrease (-5[1])in this quantity. (10[1])This quantity drops (-5[1])when the equilibrium of a bicarbonate-carbonate buffer is altered. For 10 points, increased carbon dioxide uptake causes a decrease in what quantity through ocean acidification? ■END■ (10[4])
