Organisms that use light to manufacture their own food are called:

1. The prefix photo- records the energy source and the suffix -troph the feeding style. 2. An organism that builds its own food is an autotroph. 3. Because they use light to manufacture their own food, they are called photoautotrophs, literally self-feeders using light. 4. Chemoautotrophs build sugars from inorganic chemical energy instead of light. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 8 'Photosynthesis', sections 8.1-8.3_
