A producer is like... a green plant or bacterium (plural for bacteria) and it's part of the first level of the food chain. Phototrophs and chemotrophs are two major producers. Phototrophs use the energy from the sun to convert carbon dioxide into carbohydrates, in other words, photosynthesis. Chemotrophs are almost microscopic- they are found in places where water and light are scarce (or rare) or even not there at all.
