  • Uses And Uses Of Photosynthesis

    Background: Photosynthesis is the process by which photoautotrophs convert photons of kinetic light energy into potential chemical energy (food) by synthesizing glucose from water and carbon dioxide and releasing oxygen as a waste product. Sunlight radiation travels in waves but acts like particles of energy called photons. During photosynthesis, these photons are harvested to produce chemical energy in the form of carbohydrates. Autotrophs are “self-feeder” organisms that make their own food
