- 10. Multiple Choice
Explain the concept of ocean acidification and its impact on marine life.
Ocean acidification is the process of the ocean becoming more acidic due to the absorption of carbon dioxide from the atmosphere. This can have detrimental effects on marine life, particularly on organisms with calcium carbonate shells or skeletons.
Ocean acidification has no impact on marine life and is a natural process.
Ocean acidification is the process of the ocean becoming less acidic due to the absorption of carbon dioxide from the atmosphere.
Marine life actually benefits from ocean acidification as it provides more nutrients for growth.
