Answer:

Cellular Respiration and Photosynthesis

Explanation:

Cellular respiration uses oxygen and sugar and turns it into water and carbon dioxide, photosynthesis uses water and carbon dioxide and turns it into oxygen and sugar.
That would be photosynthesis and cellular(aerobic) respiration.

The products of photosynthesis(oxygen and glucose) are the reactants of cellular respiration which uses that to make CO2, water and energy(ATP)
