Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide ($CO_2$), and water to produce glucose and oxygen. This process reduces the amount of $CO_2$ in the atmosphere. Cellular respiration, on the other hand, is the process by which cells break down glucose to produce energy, carbon dioxide, and water. It increases the amount of $CO_2$ in the atmosphere.
