Which reservoir of the carbon cycle changes the most and the quickest?

The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean's surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths.

carbon C,, comes from burning of hydrocarbons ,,which is a component of oxygen hydrogen and carbon ,,,the reservior in which carbon changes is coke,,,carbon flow into the atmosphere is less than the one released and these causes global warming,,due to blockage of the ozone layer leading to rain acid which leads to corrosion of ironover 300 years the role of ocean has changed,the convectional currents from the see meets carbon due to oxidation,,Co is formed C +O=C0,, ,in 2014,,the rate of global warming increased due to imcrease of release of carbon to the atmosphere,,,

please can i have brainliest

Explanation:

what's the question?

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
