I need quick and short answers for these questions:
-How do you think ocean acidification affect marine animals with shells?
– How do you think ocean acidification might affect the marine food web?
– What can we do to reduce ocean acidification?

2. If the ocean’s acid levels rapidly grow higher, the ecosystem might not be able to adapt to the changes quick enough. Various species including plankton which are near the bottom of food chains will decrease in number, compromising the diet of other marine life. This could cause lots of species to become endangered and also sort of make and imbalance in the food web. Many people also rely on the same food web for their diets.
3. It is caused by burning fossil fuels mainly because of carbonic acid formed by carbon dioxide released into the air. we could lower our fossil fuel consumption and also burn them more efficiently so that sulphur and other substances can’t cause a problem. this will also reduce acid rain which is a problem to coasts located near big cities.
1. Calcium carbonate dissociates in acidic conditions to calcium Ions associated with the acid, (CaCl probably) CO2 and water, so marine animals will literally dissolve in acidic conditions. This already happens naturally, but the rate of increasing it’s shell has always been larger to the shell which dissolves, but in acid conditions, the rate of dissolving is greater than the one which makes the shell.
2. Coral, plankton, and marine animals that depend on calcification are affected by pH and therefore their populations decline, making it less available for predators to hunt them, and therefore, starve.
3. Acidification of the ocean is caused by the increase of atmospheric CO2 that dissolves into the water. 40% of CO2 we send to the atmosphere is absorbed by water, therefore one option is reducing CO2. A solution could be using Carbon negative fuels or Iron fertilization of the ocean.
Carbon negative fuels: Carbonic acid can be extracted from seawater as carbon dioxide for use in making synthetic fuel. If the resulting flue exhaust gas is subject to carbon capture, then the process is carbon negative over time, resulting in permanent extraction of inorganic carbon from seawater and the atmosphere with which it is in equilibrium. Based on the energy requirements, this process is expected to cost about $50 per tonne of CO2.
Iron fertilization
It has been proposed that iron fertilization of the ocean could stimulate photosynthesis in phytoplankton. The phytoplankton would convert the ocean’s dissolved carbon dioxide into carbohydrate and oxygen gas, some of which would sink into the deeper ocean before oxidizing. More than a dozen other open-sea experiments confirmed that adding iron to the ocean increases photosynthesis in phytoplankton by up to 30 times. While this approach has been proposed as a potential solution to the ocean acidification problem, it could potentially mitigate some amount of surface ocean acidification at the cost of increasing acidification in the deep ocean.
