Answer:
D
Explanation:
Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons
Facilitated diffusion does not use cellular energy.
Since the transportation of molecules occurs through the concentration gradient, it doesn’t use cellular energy for transportation of molecules.
