An autotroph or primary producer is an organism that produces complex organic compounds such as carbohydrates, fats, and proteins using carbon from simple substances such as carbon dioxide, generally using energy from light photosynthesis or inorganic chemical reactions chemosynthesis. Chemoheterotrophs, for example, would be organisms that gain organic carbon from external sources and use chemical reactions to produce energy for biological processes. Autotrophs make food for their own use, but they make enough to support other life as well. They either focus on eating plants directly for food or may even eat other species to gain energy indirectly. In this article we will discuss about autotrophic and heterotrophic plants.
