How Would Acidification of Seawater Affect Marine Organisms

Question

How would acidification of seawater affect marine organisms?
A) Acidification would increase dissolved carbonate concentrations and promote faster growth of corals and shell-building animals.
B) Acidification would decrease dissolved carbonate concentrations and promote faster growth of corals and shell-building animals.
C) Acidification would increase dissolved carbonate concentrations and hinder growth of corals and shell-building animals.
D) Acidification would decrease dissolved carbonate concentrations and hinder growth of corals and shell-building animals.
E) Acidification would increase dissolved bicarbonate concentrations, and cause increased calcification of corals and shellfish.

Accepted Answer

Acidification of seawater would decrease dissolved carbonate concentrations, leading to hindrance in growth of corals and shell-building animals. This is because these organisms require dissolved carbonate ions to form their protective shells and skeletons. Acidification also makes it difficult for these organisms to build and maintain their structures.
