Answer:
B-oceans
Step-by-step explanation:
The biggest CO2 sink on the planet is not really the forest masses. It is the ocean. In fact, the increase in atmospheric CO2, is falling into the ocean with the rain, that CO2, is dissolved in the Sea, and is acidifying it, which together with the general increase in temperatures, is already generating very serious problems in certain ocean regions (Massive deaths in the great coral reefs), and we run the risk of loading ourselves, the entire marine trophic chain, and we already bundle it completely brown, if we lose that sink that fixes CO2.
Carbon is taken from the atmosphere in several ways:
* When the sun shines, plants perform photosynthesis to convert carbon dioxide into carbohydrates, releasing oxygen in the process. This process is more prolific in relatively new forests, where tree growth is still rapid.
* On the surface of the oceans, near the poles, seawater acts as a refrigerator and more carbonic acid is formed when CO2 becomes more soluble. This is connected to the thermohaline circulation of the ocean, which transports dense surface water into the ocean.
* In upper areas of the ocean with high biological productivity, organisms convert reduced carbon into tissues, and carbonates into hard body parts such as shells and shells. These compounds are, respectively, oxidized (tissue pump) and dissolved again (carbonate pump) at mid-ocean levels below where they formed, causing a downward flow of carbon.
* Erosion of silicate rock. Carbonic acid reacts with eroded rock to produce bicarbonate ions. The bicarbonate ions produced are transported to the ocean, where they are used to make marine carbonates. Unlike CO2 dissolved in equilibrium or in dead tissues, erosion does not move carbon to a reservoir from which it can easily return to the atmosphere.
