Go through the process of PHOTOSYNTHESIS.
Carbon dioxide enters the food web through the stoma of green leaves where it's absored where it uses the energy og yhe sun to form sugars. From there it begins to serve many functions in the tree. Take many forms in the tree. Sugarss combine to build more complex moleculess... Plants create their own food using the energy from sunlight to combine water with carbon dioxide from the atmosphere. Carbon is stored as sugar which the plant burn for energy. or can beccome part of more complex molecules, like cellulose.   Oxygen is released in the process as a waste product. But, did you know that 50% of the carbon stored by plants will return to the atmosphere through respiration as the plant lives and grows?

Go through the process of DIFFUSION.
Through the random motion of molecules carbon can freely cross the boundary between air ocean surface. ONce suspended in the water it can react with other ... Gaseous carbon dioxide may dissolve into the ocean surface, especially with the crashing of waves or in extreme ocean storms. There's a dynamic flux at boudary o concentrations. If there's more of one thing on one side it's more likely to go to the other. Sublimation Most of the carbon on Earth resides in the oceans There's 50 times more carbon in the ocean than in the atmosphere or biomass. .
