The correct answer would be Light energy or sunlight.
Explanation:
Photosynthesis is a complex process that takes place when plants convert sunlight into glucose or chemical energy. The photosynthesis equation states that the combination of carbon dioxide and water in the presence of light energy produces glucose and oxygen.
The photosynthetic reaction can be stated as:
6CO₂ + 6H₂O + light energy ⇒ C₆H₁₂O₆+6O₂
Thus, the correct answer would be light or sunlight.
