According to Table 27.1, which of the following accurately describes a photoheterotroph?

  • A: Obtains energy from light and uses CO2 as a carbon source.
  • B: Obtains energy from organic compounds and uses organic compounds as a carbon source.
  • C: Obtains energy from light and uses organic compounds as a carbon source.
  • D: Obtains energy from inorganic chemicals and uses CO2 as a carbon source.

Explanation

As detailed in Table 27.1, photoheterotrophs are characterized by using light as their energy source and organic compounds as their carbon source. This distinguishes them from photoautotrophs which use CO2 for carbon , chemoautotrophs which use inorganic chemicals for energy , and chemoheterotrophs which use organic compounds for both energy and carbon .
