The Results of the Coccolithophorid Experiment Done by Riebesell and Colleagues

The results of the coccolithophorid experiment done by Riebesell and colleagues showed that:

A) increasing CO₂ levels lead to incomplete or poorly formed calcium carbonate scales of coccolithophorids.
B) increasing pH levels lead to decreased calcification of coccolithophorid scales.
C) decreasing CO₂ levels lead to deformed coccolithophorid scales.
D) decreasing pH levels lead to significantly reduced growth rates.
E) None of the answer options is correct.
