process whereby plants use light energy to produce food
Photosynthesis, Respiration, Transpiration Plants are self-sufficient. They make their own food thru the process of photosynthesis using light energy to make sugars from carbon dioxide (C02) and water (H20).hotosynthesis. A primary difference between plants and animals is the plant s ability to manufacture its own food. In photosynthesis carbon dioxide from the air and water from the soil react with the sun s energy to form carbohydrates (sugars and starches).
