Producers are organisms (usually plants) that utilize photosynthesis to produce their own food supply.
Photosynthesis is a process that uses photons from the sunlight to turn glucose and oxygen into carbon dioxide and energy. It basically is a process that uses light energy to make a usable food source, and it takes place in the cells of a chloroplast.
Chlorophyll is a green pigment found inside of plants' chloroplasts that absorbs light photons, allowing photosynthesis to take place.
