(22 points! ) why does the transfer of carbon and oxygen take place? to ensure new forms of the two elements develop over time to maintain the ecosystem and make the earth habitable to life to ensure the oceans expand to ensure that the ozone layer never depletes

The correct option is this: TO MAINTAIN THE ECOSYSTEM AND MAKE THE EARTH HABITABLE TO LIFE.
Both plants and animals used carbon and oxygen. The oxygen used by humans is produced by plants while the carbon dioxide produce by human is used by plant to carry out the process of photosynthesis. Thus, the transfer of these two elements is necessary to maintain life on earth.
