Photosynthesis and respiration

Photosynthesis is when plants take sunlight and go through a chemical reaction that makes sugar for them. the equation for photosynthesis is 6CO2 + 6H2O + Energy ® C6H12O6 + 6O2 and respiration is the reverse of photosynthesis. The equation is C6H12O6 + 6O2 ® 6CO2 + 6H2O + Energy. It's when sugar is broken down into water, carbon dioxide, and energy. The result of photosynthesis is sugar and oxygen. Humans breathe in the oxygen made by plants through photosynthesis and go through respiration. They Take the oxygen and adds carbon from their body and make carbon Dioxide, which makes the entire cycle start all over again. Photosynthesis is making energy and sugar from carbon dioxide, and respiration is the process of removing carbon dioxide by taking in oxygen.
