Explanation:

Photosynthesis takes in carbon dioxide ($CO_2$) as an input gas. It uses light energy to convert $CO_2$ and water ($H_2O$) into glucose ($C_6H_{12}O_6$) and releases oxygen ($O_2$) as a by - product. The chemical equation is \(6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+6O_2\).

Cellular respiration takes in oxygen ($O_2$) as an input gas. It breaks down glucose ($C_6H_{12}O_6$) to release energy (in the form of ATP), and releases carbon dioxide ($CO_2$) and water ($H_2O$) as by - products. The chemical equation is \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2+6H_2O + \text{Energy}\).

Answer:

• Photosynthesis:
• Gas Input: Carbon dioxide ($CO_2$)
• Gas Output: Oxygen ($O_2$)
• Cellular Respiration:
• Gas Input: Oxygen ($O_2$)
• Gas Output: Carbon dioxide ($CO_2$)
