Explanation:

Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.

Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.
