Why is photosynthesis important? Original source of all important fuels Oils, Coal, Wood, Natural Gas Source of all foods, since all animals are dependent on plants at some point
3 important processes of Photosynthesis Transforms light energy from the sun into chemical energy Fixes carbon dioxide into sugar (future energy source) Produces oxygen as a by- product
Energy Transformation Earth receives energy from sun
Carbon Fixation Photosynthesis takes CO2 and converts it (through plants) into carbohydrates. Plants convert ~620 bil tons per year
Oxygen Production Plants are the primary source of oxygen world wide Oxygen is a by product of plants!
