1. The growth and survival of calcareous phytoplankton will be adversely affected.
2. The growth and survival of coral reefs will be adversely affected.
3. The survival of some animals that have phytoplanktonic larvae will be adversely affected.
4. The cloud seeding and formation of clouds will be adversely affected.

• B. 2 only
• C. 1 and 3 only
• D. 1, 2, 3 and 4

Answer 1

The correct option is A 1, 2 and 3 only

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Acidification can have several negative effects on oceanic life forms. For example, a drop in the pH of the ocean water can make it difficult for certain species of coastal life to create their exoskeletons, which is essential for their survival. Therefore, ocean acidification can contribute to a loss of biodiversity.
Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.
Cloud seeding and formation has nothing to do with acidification of oceans.
