True or False Statements
Declining coral calcification rates suggests a decrease in the level of bicarbonates and an increase in the level of carbonates in seawater. Blanktarget 1 of 6
As atmospheric CO2 concentrations reach 840 ppm, or three times the preindustrial level, the calcification rate will be reduced to 30 mmol/m2/day. Blanktarget 2 of 6
Although not reflected in the graph, based on how ocean acidification works, the relationship between oceanic pH and coral reef calcification rates can be predicted to be positively (or directly) correlated. Blanktarget 3 of 6
Coral reef calcification rates are projected to steadily decline as atmospheric CO2 concentrations increase. Blanktarget 4 of 6
The data in this graph could also be plotted as a pie chart. Blanktarget 5 of 6
As atmospheric CO2 concentrations reach 560 ppm, or double the preindustrial level, the coral calcification rate is projected to be reduced by more than two-thirds from what it was at the preindustrial level. Blank

Let's evaluate each statement:
1. **Declining coral calcification rates suggests a decrease in the level of bicarbonates and an increase in the level of carbonates in seawater.**
**False** - Declining coral calcification rates are typically associated with increased levels of carbon dioxide in the ocean, leading to ocean acidification, which decreases carbonate ion concentrations rather than increasing them. Bicarbonate levels may increase, but the overall carbonate availability for calcification diminishes.
2. **As atmospheric CO2 concentrations reach 840 ppm, or three times the preindustrial level, the calcification rate will be reduced to 30 mmol/m2/day.**
**True or False** - This statement needs context from specific research or data to be determined. It's possible that such a prediction exists, but it would depend on empirical data at the time of the claim.
3. **Although not reflected in the graph, based on how ocean acidification works, the relationship between oceanic pH and coral reef calcification rates can be predicted to be positively (or directly) correlated.**
**False** - The relationship is generally negatively correlated; as oceanic pH decreases (more acidic), calcification rates decline.
4. **Coral reef calcification rates are projected to steadily decline as atmospheric CO2 concentrations increase.**
**True** - This is supported by research indicating that rising atmospheric CO2 levels lead to increased ocean acidification, negatively impacting coral calcification.
5. **The data in this graph could also be plotted as a pie chart.**
**False** - Coral calcification rates over time are typically represented as continuous data better suited for line graphs or bar graphs, rather than categorical data suited for pie charts.
6. **As atmospheric CO2 concentrations reach 560 ppm, or double the preindustrial level, the coral calcification rate is projected to be reduced by more than two-thirds from what it was at the preindustrial level.**
**True or False** - Similar to statement 2, this would need specific data to be confirmed. It is plausible based on existing research showing significant declines at high CO2 levels, but without the exact data, it cannot be definitively stated as true or false.
In summary:
1. False
2. Context-dependent (True or False)
3. False
4. True
5. False
6. Context-dependent (True or False)
