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 (“kok-oh-LITH-oh-fohrs”). Aragonite-using organisms are the first to be affected by changes in this quantity. (*) Coral bleaching is exacerbated by a global decrease in this quantity. This quantity drops 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■
ANSWER: oceanic pH [prompt on ocean acidification or acidity or alkalinity before "acidification"; prompt on any description of CO2 levels like concentration of carbon dioxide or concentration of CO2 or dissolved inorganic carbon or total inorganic carbon before "carbon dioxide"]
