Answer
1) Photoautotrophs use light and carbon dioxide to synthesize organic sugars via photosynthesis.
2) Photoheterotrophs use light for energy but use organic compounds for their carbon source.
3) Chemoautotrophs get their energy by oxidizing inorganic substances and perform carbon fixation
4) Chemoheterotrophs receive carbon from complex organic compounds synthesized by other organisms and obtain energy from breaking down these organic compounds.
