Answer:
Plants make food by a process known as photosynthesis. As the name suggests, photo or light energy is used in this process of synthesis. Plants use three ingredients: sun light, carbon dioxide (CO2) and water (H2O) to make food (sugars). The following takes place during photosynthesis:
6CO_2 + 6H_2O + (light) -> C_6H_(12)O_6 + 6)_2
