Urgent ! question 1 plants make it through photosynthesis. a chemical reaction. what are the starting substances of the reaction? carbon dioxide, solar energy, oxygen carbon dioxide, water, solar energy hydrogen, oxygen, carbon oxygen, solar energy, water question 2 what are the products of photosynthesis hydrogen, oxygen, carbon glucose and oxygen carbon dioxide, water, solar energy oxygen, solar energy, glucose question 3 where is energy in the products of photosynthesis the oxygen has a lot of kinetic energy the bond of glucose molecule store chemical energy the bond of oxygen molecule store electric energy glucose has a lot of mechanical energy question 4 how does photosynthesis use solar energy the solar energy just a reaction and then its gone solar energy is converted to chemical energy in chemical bonds of the glucose molecule solar energy is converted to heat the solar energy is used up the bonds of the carbon dioxide and water question 5 what kind of energy is required for photosynthesis to occur energy from the nutrient in the ground thermal energy solar energy energy stored in chemical bonds
