Answer:
Chemical energy, carbon dioxide.
Step-by-step explanation:
Photosynthesis is the process through which plants, some bacteria, and some others organisms made their food by the use of energy from sunlight and convert it into chemical energy to produce sugar. The conversion of sunlight energy into usable chemical energy, is held by chlorophyll. The photosynthetic process uses water as an electron donor and releases the oxygen.
The overall reaction of photosynthesis is:
6 molecules of water + 6 six molecules of carbon dioxide with the help of light, produce one molecule of sugar + six molecules of oxygen
