Answer:
Option (1)
Explanation:
The amount of carbon present in the ocean is inversely proportional to the pH level of water. This COâ‚‚ amount present in the atmosphere may rise because of various types of human activities, that results in the increasing amount of dissolved COâ‚‚ in the oceans. This in turn, again decreases the pH level of water. This water when reduces, it becomes saturated with the COâ‚‚ and it also diminishes the source of calcium carbonate. Â
The increase in the ocean acidification leads to the significant reduction of the reef-building corals. As a result of which the temperature of the water increases and they are not able to assemble their skeletal parts.
Hence, the correct answer is option (1).
