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 (-5[1])by a global decrease (10[2])in (-5[1])this quantity. This quantity drops when the equilibrium of a bicarbonate-carbonate buffer is altered. (10[1])For 10 points, increased carbon dioxide uptake causes a decrease in what quantity through ocean acidification? ■END■ (0[1])

ANSWER: oceanic pH [prompt on ocean acidification or acidity or alkalinity before "acidification"; prompt on concentration of carbon dioxide or concentration of CO2 or dissolved inorganic carbon or total inorganic carbon before "carbon dioxide"]
