- Photosynthesis happens when a leaf absorbs light energy and in this process it combines CO2 with water to form glucose and oxygen which are given off as waste molecules.
- CO2 + H2O ---> C6H12oO6 + O2 -> Excretion
- Glucose and Oxygen happen through enzyme reactions, the glucose is broken down and forms ATP.
- Carbon dioxide is a metabolic waste and is excreted.
- C6H12oO6 + O2 ---> ATP + H2O + H2O -> Respiration
- Glucose molecule are broken down and energy is used to form ATP and get the waste of carbon dioxide and water to be given off.
- This waste process is called Excretion.
