Photosynthesis vs chemosyntheis - ANS is the process by which producers use solar energy to convert carbon dioxide into glucose vs deep-sea producers uses chemical energy to make organic molecules. Photosynthesis: - ANS is an important mechanism for capturing and storing energy. Plant cells have organelles called chloroplasts, containing the pigment chlorophyll, which are able to capture the solar energy. The solar energy excites electrons in the chlorophyll, triggering a seri...
