Increased carbon in the oceans has caused the ph levels of the water to decrease. what is the largest impact of this ocean acidification on marine life?

increased coral bleaching
increased fish predation
increased marine bird migration distances
increased marine mammal hibernation time

Option (1)

Explanation:

The amount of carbon present in the ocean is inversely proportional to the pH level of water. This CO₂ amount present in the atmosphere may rise because of various types of human activities, that results in the increasing amount of dissolved CO₂ in the oceans. This in turn, again decreases the pH level of water. This water when reduces, it becomes saturated with the CO₂ and it also diminishes the source of calcium carbonate.  

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).
