Answer

Photosynthesis and cellular respiration are interdependent because each process’s products are the other’s reactants, creating a continuous biological cycle. Explanation 1. Identify the products and reactants of each process Photosynthesis produces glucose (C_6H_{12}O_6) and O_2; cellular respiration uses these as reactants. Cellular respiration produces CO_2 and H_2O, which are reactants for photosynthesis. 2. State the relationship using formulas **Photosynthesis:** 6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2 **Cellular Respiration:** C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{energy} 3. Explain interdependence The output of one process is the input of the other, forming a cycle that sustains life.
