They pump hydrogen ions (H +) out of this space to produce more carbonate ions (CO 32-) ions that bond with (Ca 2+) ions to make calcium carbonate (CaCO 3) for their skeletons. Because there are more HCO 3- ions but fewer CO 32- ions in acidified seawater, the corals have to expend more energy to pump out H + ions from …
