Plants transform the sun's energy into chemical energy, which is trapped inside the bonds of carbon molecules formed from atmospheric carbon dioxide and water during photosynthesis. Yes, carbon dioxide from the air we breathe ends up in "food" molecules (called glucose), each of which includes six carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms). There is, however, a downside to this. Plants utilise the energy contained in part of the carbon molecules they create to keep themselves alive and proliferate.Explanation:
