47. With reference to ocean acidification, which of the following statements are true?
i) Rising greenhouse gases are increasing ocean acidification.
ii) Productivity of corals will increase because of the increase in acidity of the ocean.
Options:
Explanation:
When carbon dioxide dissolves in this ocean, carbonic acid is formed. This leads to higher acidity, mainly near the surface
As human activities pump ever-greater quantities of carbon dioxide into the atmosphere, our ocean waters absorb that gas, which results in ocean acidification.
Shell-forming animals including corals, oysters, shrimp, lobster, many planktonic organisms, and even some fish species could be gravely affected. This is because numerous marine organisms such as corals, mollusks, crustaceans and seaurchins rely on carbonate ions to form their calcareous shells or skeletons in a process known as calcificatio
