How does ocean acidification weaken the shells of organisms, like pteropods?

• It reduces the amount of oxygen in the water causing the pteropod to grow too quickly for its shell.

• It increases the amount of solar radiation in the water causing the shell to burn.

• It decreases the amount of calcium carbonate in the water causing the shell to be underdeveloped.

• It increases the amount of calcium carbonate in the water causing the shell to become too thick.
