Quizplus · Accepted Answer

The first step in the use of carbon by living organisms occurs in green plants during the process of photosynthesis, where carbon dioxide is converted into organic compounds such as sugars, which are then used by other organisms for energy and growth. Soil bacteria and other microorganisms also play a role in the carbon cycle, but they do not initiate the process of photosynthesis. Humans, vertebrates, and invertebrates are consumers in the carbon cycle and do not directly use carbon as the first step.
