Archaeons are not known to incorporate (fix)carbon dioxide.

Question

Quizplus · Accepted Answer

Archaeons are known to incorporate carbon dioxide in a process called carbon fixation. Some archaeons use a form of carbon fixation called the 3-hydroxypropionate/4-hydroxybutyrate pathway, while others use the reverse TCA cycle. This ability allows archaeons to survive in extreme environments where other organisms cannot, as they can create their own organic compounds from inorganic carbon sources.
