The percentage of radiant energy entering the reaction site in photosynthesis which is converted into potential energy is 35%.
During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy.
Radiant energy is the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment. Radiant energy sources include the entire electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, sunlight and heat.
