Answer 1

The correct response is:

The Carbon Dioxide makes the water more acidic and it dissolves their shells.

Excess carbon dioxide in the atmosphere can lead to increased levels of carbonic acid in ocean water, which lowers the pH and increases acidity. This acidification can negatively affect marine animals that rely on calcium carbonate to build their shells, making them more vulnerable as their shells can dissolve or become weaker.
