Verified step by step guidance1
Understand that photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose.
Recall the basic inputs (reactants) required for photosynthesis: plants need light energy, water (H\_2O), and carbon dioxide (CO\_2).
Recognize that nitrogen gas (N\_2), oxygen (O\_2), and glucose (C\_6H\_{12}O\_6) are not direct inputs for photosynthesis; oxygen and glucose are actually products or involved in other processes like respiration.
Identify that the correct combination of inputs for photosynthesis is light energy, water, and carbon dioxide.
Confirm that the overall photosynthesis equation is: 6CO\_2 + 6H\_2O + light energy \rightarrow C\_6H\_{12}O\_6 + 6O\_2, which supports the choice of light energy, water, and carbon dioxide as inputs.
