Consider the following statements regarding Ocean Acidification:1. Oce...
Ocean acidification is a process that occurs when carbon dioxide (CO2) is absorbed by seawater, resulting in a decrease in pH levels. This phenomenon has significant impacts on marine ecosystems and organisms. Let us analyze each statement and determine their accuracy.
1. Ocean acidification increases the amount of carbonate in oceans and suffocates corals.
- This statement is partially correct. Ocean acidification reduces the availability of carbonate ions, which are essential building blocks for coral reefs and other marine organisms with calcium carbonate skeletons or shells. As the pH decreases, the concentration of carbonate ions decreases, making it more challenging for corals and other calcifying organisms to build and maintain their structures. However, it is important to note that ocean acidification does not suffocate corals. Instead, it impairs their ability to grow and may lead to the dissolution of their existing structures over time.
2. Animals like Starfish, Sea butterflies, and Mussels are benefited from ocean acidification.
- This statement is incorrect. Ocean acidification primarily has negative impacts on marine organisms, particularly those that rely on calcium carbonate structures such as shells and skeletons. Animals like starfish, sea butterflies (a type of pteropod), and mussels are vulnerable to the effects of ocean acidification. The decreased availability of carbonate ions can hinder their ability to build and maintain their shells or skeletons, making them more susceptible to predation and other environmental stressors.
3. Currently, the pH of the world's oceans is slightly less than 7.
- This statement is incorrect. The pH scale ranges from 0 to 14, with 7 being neutral. The pH of the world's oceans is slightly above 7, typically around 8.1 on average. However, due to ongoing carbon dioxide emissions and ocean acidification, the pH levels are gradually decreasing, making the oceans more acidic over time.
In summary, statement 1 is partially correct, statement 2 is incorrect, and statement 3 is incorrect. Therefore, option 'D' - 1, 2, and 3 is the correct answer.

Consider the following statements regarding Ocean Acidification:1. Oce...
- As carbon dioxide (CO2) dissolves in seawater, it forms carbonic acid, decreasing the ocean’s pH, a process collectively known as ocean acidification.
- Present ocean acidification occurs approximately ten times faster than anything experienced during the last 300 million years, jeopardizing the ability of ocean systems to adapt to changes in ocean chemistry due to CO2.
- Ocean acidification has the potential to change marine ecosystems and impact many ocean-related benefits to society such as coastal protection or provision of food and income.
- Effects of Ocean Acidification on the marine ecosystem
- Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve. Hence statement 1 is not correct.
- Ocean life vulnerable to ocean acidification includes Starfish, Sea butterflies, Mussels, Clams, Oysters, Scallops, Sea urchins, (pteropods) Shell-forming algae, and amoebas. Hence statement 2 is not correct.
- Prior to the Industrial Revolution, the average ocean pH was about 8.2. Today, the average ocean pH is about 8.1. This might not seem like much of a difference, but the relationship between pH and acidity is not direct. Each decrease of one pH unit is a ten-fold increase in acidity. Hence statement 3 is not correct.
- This means that the acidity of the ocean today, on average, is about 25% greater than it was during preindustrial times.
