What is the role of shell-building marine creatures in regulating climate?

A.

their shells form the hydrocarbon fuels that release greenhouse gases when burned

B.

they utilize the carbon dioxide released while respiring to build their shells

they help to remove carbon dioxide through calcification

D.

they help to remove carbon dioxide through photosynthesis

they utilize the carbon dioxide released while respiring to build their shells

Explanation:

Ocean acidification affect Marine organisms negatively,by making their shells and skeletons to dissolve. To make calcium carbonate, the shell building animals like corals and oysters combine one of their calcium to carbonates in the sea water where they release carbondioxide and water during the process and uses its to build shells.
