why does your life depend on photosynthetic organisms
PHOTOSYNTHESIS. INTRODUCTION. Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria.n so doing, photosynthesis provides the basic energy source for virtually all organisms.
