Question

Quizplus · Accepted Answer

Foraminifera are tiny marine organisms that build shells with calcium carbonate. By studying the composition of these shells, scientists can determine the pH levels (acidity) of seawater in the past. Recent studies have shown that the pH levels of the oceans are decreasing, meaning they are becoming more acidic. This is due to the absorption of excess carbon dioxide from the atmosphere, leading to ocean acidification.
