7. Autotroph

Autotrophs are organisms that produce their own food, hence their other name, producers. Typically, these organisms obtain their energy by synthesizing glucose through photosynthesis. When sunlight is not present however, certain autotrophs can use the energy of inorganic reactions to produce glucose, in a process known as chemosynthesis. Although autotrophs do not eat other organisms, they are consumed by heterotrophs, or consumers. An example of an autotroph that is eaten by consumers, even humans, is the rosemary plant seen above.
