Organisms in an estuary, including phytoplankton, seagrasses, crustaceans, and mollusks, are all exposed to increasing acidity as atmospheric CO₂ levels rise.What effect does the increased acidity likely have on these organisms?

Question

Quizplus · Accepted Answer

Increased acidity, primarily due to rising CO2 levels, can lead to weaker shells in crustaceans and mollusks because it reduces the availability of carbonate ions needed for shell formation. Phytoplankton and seagrasses might increase photosynthesis due to higher CO2 levels, acting as a carbon source.
