Question

question 4 1 pts choose the incorrect answer: what happens when carbon dioxide is added to seawater? seagrasses thrive calcium decreases ph decreases carbonate ions decrease hydrogen ions increase

Explanation:

When carbon - dioxide is added to seawater, it reacts with water to form carbonic acid. This increases hydrogen ions, decreases pH, and decreases carbonate ions. Also, the availability of calcium carbonate for organisms like seagrasses can be affected negatively, so seagrasses do not thrive. And the addition of carbon - dioxide does not directly cause a decrease in calcium in seawater in the sense described here.

Answer:

A. Seagrasses thrive
