What statement best summarizes the relationship between photosynthesis and cellular respiration?

• takahiro: For the answer to the question above, well basically Photosynthesis is a process of a plant on how to get food and it gets the energy from sunlight and putting it together with large sugar molecules like CO2 and H2O.
  
  Cellular respiration occurs when organisms break down large sugar molecules to use the energy to do the work and release the waste products such as the Carbon Dioxide(CO2) and Water(H2O.)
