The plants need sunlight in order for photosysthesis to occur. It needs the source of energy from the sun in order to grow and produce oxygen for us.

To perform photosynthesis; a process of conversion of solar energy into usable chemical energy
6CO2 + 12H2O + sunlight ---> 6O2 + C6 H12O 6 + 6H2O

how is oxygen produced for us to breathe? From Plants and Trees. the plants need the sun light to draw energy from that light, then use photonsynthisis to turn that energy into oxygen for humans to breathe. without oxygen, we die. carbon monoxide is also sucked in by the plants, and reproduced into oxygen again and released back out into the atmosphere.
