Autotrophs collect energy from the sun and make energy through photosynthesis. (Purves, 962) Autotrophs are the organisms that produce energy by themselves by their chemical reactions. (Auto means self and troph means nutrition in Greek). [1]

Usually, producers occupy the autotrophic level. The autotrophs are the most important organism in an ecosystem. They obtain nitrogen from other organisms but not energy. The plants or the autotrophs use sources from the environment such as the sunlight and inorganic compounds to live. They become important resources for the heterotrophs. (Purves, 717)

Because the autotrophs gain energy by photosynthesis, they are called photosynthesizers. Primary producers are another name to the autotrophs, because they are in first position in the trophic level. (Purves, 1060)
