Answer 2

Answer:

For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground), and light (usually from the sun).

                                       sunlight

carbon dioxide + water ------------->  glucose + oxygen

                           sunlight

6CO2 + 6H2O ---------------> C6H12O6 + 6O2
