Web4 feb. 2024 · Volcanic activity or the burning of fossil fuels by humans can return this sequestered carbon to the atmosphere as CO 2. CO 2 from the atmosphere can then dissolve into the sea, and there the cycle can start again. Blue carbon is the part of the carbon cycle that involves sea-life. This part of the cycle happens in three stages. WebThe natural carbon cycle is kept very nearly in balance; animals and plants emit CO 2 into the atmosphere through respiration, while plants absorb it through photosynthesis. The ocean also cycles CO 2 with the atmosphere, in an almost perfect balance. hillaryburyWebVolcanic ash, aerosols, and mineral dust can also be significant phosphate sources, though phosphorus has no real gas phase, unlike other elements such as carbon, nitrogen, and sulfur.
