Examples of photoautotroph in the following topics:

  • Photoautotrophs and Photoheterotrophs

    • Photoautotrophs and photoheterotrophs are organisms that rely on light as their source of energy to carry out cellular processes.
    • Photoautotrophs are organisms that carry out photosynthesis.
    • Most of the well-recognized phototrophs are autotrophs, also known as photoautotrophs, and can fix carbon.
