Specify the three ways in which prokaryotes obtain energy for cellular respiration

Autotrophs use photosynthesis to fix light energy in organic molecules the synthesize from carbon dioxide.

chemo-organo-hereotrophs use the energy stored in organic molecules from other organisms

chemo-autotrophs and chemo-hereotrophs use the energy from redox reactions of organic and inorganic compounds in the environment.
