Final answer:
Light energy is converted into chemical energy during the first stage of photosynthesis, which is then stored in glucose.
Step-by-step explanation:
In the first stage of photosynthesis, light energy is converted into chemical energy. This chemical energy is stored in the form of glucose, which is a simple carbohydrate. Plants and photoautotrophs harness specific wavelengths of light to perform this energy transformation, which is critical for their ability to create food from inorganic substances.
