Consider the following statements:Statement-I: Ocean acidification is ...
Explanation:
Ocean acidification is detrimental to coral reefs because it decreases the availability of calcium carbonate, which is essential for the growth and development of coral reefs.
Statement-I: Ocean acidification is detrimental to coral reefs.
- Acidification of the ocean leads to a decrease in the concentration of carbonate ions, which are necessary for coral reefs to build their calcium carbonate skeletons.
- This process weakens the coral structures, making them more susceptible to damage from storms, erosion, and other environmental stressors.
Statement-II: An increase in acidification slows the rate at which calcium carbonate is generated.
- As the ocean becomes more acidic, the chemical equilibrium between carbonate ions and bicarbonate ions shifts, making it harder for corals and other marine organisms to extract calcium carbonate from the water.
- This slower rate of calcium carbonate generation can hinder the growth and survival of coral reefs.
Conclusion:
Both Statement-I and Statement-II are correct, and Statement-I is the correct explanation for Statement-II. Ocean acidification has a direct negative impact on coral reefs by reducing the availability of calcium carbonate, which is crucial for their growth and development.

Consider the following statements:Statement-I: Ocean acidification is ...
- Increased carbon dioxide in the atmosphere is one of the recognized causes of our changing climate and it is also problematic for coral reefs. The ocean absorbs approximately one-third of the atmosphere’s excess carbon dioxide, resulting in a more acidic ocean. In order for a coral reef to grow, it must produce limestone (or calcium carbonate) at a rate that is faster than the reef is being eroded. Ocean acidification slows the rate at which coral reefs generate calcium carbonate, thus slowing the growth of coral skeletons.
- Climate change can cause sea level rise; changes in the frequency, intensity, and distribution of tropical storms; and altered ocean circulation. All of these impacts can have negative consequences for the health and diversity of reefs around the world. Hence, statement-I and statement II are correct. Also, statement II is the correct explanation for statement-I.
- A 20 percent increase above current carbon dioxide levels, which could occur within the next two decades, could significantly reduce the ability of corals to build their skeletons and some could become functionally extinct within this timeframe.
- In real terms, this does not just mean corals grow more slowly, but also that they will be less able to overcome typical pressures. Tropical coral reefs are constantly engaging in a battle to grow. Many reef dwellers actually break apart pieces of the corals’ skeletons, either to feed upon or to create homes.
