The light-independent reaction uses the energy from NADPH and ATP to produce sugar.
Explanation:
The photosynthesis is the process that fuels the entire earth the sun’s energy is used to split the water in light reactions generating ATP and NADPH, this energy is in turn used by the light independent reaction to cook the food and produce carbohydrates that is sugar.
Since the light dependent reaction generates energy for the light independent process the entire process is considered to be fueled by sunlight.
