Question

Quizplus · Accepted Answer

Carbon dioxide dissolved in ocean water is unlikely to be incorporated into a fossil fuel as it would require a series of complex geological processes over millions of years. The other options are all plausible fates of a molecule of carbon dioxide dissolved in ocean water. It could diffuse to the atmosphere, become part of a marine animal's shell, be taken up by phytoplankton through photosynthesis, or remain dissolved in the water.
