Detailed explanation-1: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).
Detailed explanation-2: -Plant carbohydrates, in the form of sugars are the energy source by which all plants carry out their major functions. All plants must photosynthesize, transpire and respire to survive. Sugar plays a vital role in all of these.
Detailed explanation-3: -Through photosynthesis, producers convert solar energy to chemical energy, energy in the chemical bonds of the food. Of all the energy a plant receives from the sun, only about three percent is converted into chemical energy.
