Detailed explanation-1: -The studies, some of which made headlines, found that acidification can disorient fish, make them hyperactive or bolder, alter their vision, and lead them to become attracted to, rather than repelled by, the smell of predators. Such changes, researchers noted, could cause populations to plummet.
Detailed explanation-2: -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.
Detailed explanation-3: -Rising levels of carbon dioxide in the atmosphere, mostly from burning fossil fuels, cause ocean acidification. When carbon dioxide is absorbed by seawater, it’s harder for corals to accrete their aragonite skeletons.
Detailed explanation-4: -Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels.
