Document Summary
How photosynthesizers capture sunlight and turn into covalent bonds which is potential. Photosynthesis is storage of light energy by covalently bonding atoms together and forming larger structures. Even microorganisms like bacteria that harness solar energy even though they don"t have chloroplasts. Can only get energy after autotrophs harness it. Some organisms in deep ocean that live off energy from thermoaquatic vents but those are few and fat between. The overall reaction use of co2, water and light energy as kinetic energy and uses it to covalently bond atoms together into larger structures. Oxygen is also produced. plants and other photosynthesizers produce oxygen. Oxygen in air comes from plants ability to split water into oxygen ions and gas. Sunlight as energy source: pure energy can have lower or higher strengths electromagnetic spectrum. Eyes observe small fraction of energy that exists in universe. The distance between crests of energy waves tells you how strong they are. visible light is what we see.
