How did primitive heterotrophs produce energy?

aerobic respiration

chemical fermentation

photosynthesis

The correct answer for the given question above is the second option. Primitive heterotrophs produce energy through chemical fermentation. Chemical fermentation is the same with the process of anaerobic respiration. This involves the breaking down of glucose into energy sources anaerobically.
