Answer/Explanation:

Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.

Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products.

Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
