The diagram summarizes the light-dependent reactions of photosynthesis.

what is the input, which is labeled x?
co2, h2o, o2, and light
co2, h2o, and light
co2 and h2o
h2o and light

The right answer is CO2, H2O, and light.

Photosynthesis is a conversion of light energy from the sun into chemical energy. This photonic biosynthesis of a carbohydrate is made from carbon dioxide CO2, water H2O, by means of light energy (from the sun).

Explanation:- Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.
