A research team conducted a project where they artificially increased the CO2 levels in tanks containing corals. They found an inverse relationship between reef building and atmospheric CO2. This experiment __________.  Options: A. is not possible. Increased CO2 should not affect the reef, as it is a relatively inert gas. B. represents the situation in the pre-industrial age, with less reef-building occurring than now C. indicates that marine ecosystems are unlikely to be affected by rising CO2 levels D. indicates that available calcium carbonate levels will increase with increasing levels of CO2 E. indicates that even though the oceans may be good sinks for CO2, there will be negative impacts of increasing levels of atmospheric CO2 beyond the greenhouse effect
