Carbon in the environment form the carbon cycle. For example, photosynthetic plants draw carbon dioxide from the atmosphere (or seawater) and build it into biomass, as in the Calvin cycle, a process of carbon fixation. Some of this biomass is eaten by animals, while some carbon is exhaled by animals as carbon dioxide. The carbon cycle is considerably more complicated than this short loop; for example, some carbon dioxide is dissolved in the oceans; if bacteria do not consume it, dead plant or animal matter may become petroleum or coal, which releases carbon when burned. Carbon can form very long chains
Ocean storage of carbon dioxide However, organisms are not only affected by the acidification of water in the presence of heightened carbon dioxide (carbon dioxide) levels. carbon dioxide itself interacts with the physiological function of individual organisms. These effects are more damaging than those associated with changes in pH of environment. When carbon dioxide enters organisms, through diffusion across tissue, it becomes internally accumulated which can then cause anesthesia and, depending on the concentration of carbon dioxide, death. The internal accumulation will also cause organisms to experience blood acidification. This weakens organisms' ability to uptake oxygen and consequently weakens their performances. This effect is more
