Bio-Prokaryotes-Metabolic classification

First source of carbon?

Autotroph= gains carbon from INORGANIC material

Second source of carbon?

Heterotroph = comsumes OTHER organisms to get organic molecules

First source of energy?

Phototroph = derives energy from sun

Second source of energy?

Chemotroph = energy from Redbox reaction (passing electrons)

First type of oxygen source?

Obligative aerob = NEEDs oxygen to survive = aerobic respiration

Second source of oxygen?

Facultative = can live with or without oxygen

Third source of oxygen?

Obligate anaerobe = oxygen is toxic = anaerobic respiration

Photoautotroph

Sunlight and inorganic molecules

ex. cyanobacteria

Chemoautotroph

Redox reactions and inorganic molecules 

ex. deep sea bacteria

Photoheterotroph

Sunlight and organic matter

ex. heliobacteria

Chemoheterotroph

Redox reactions and organic matter 

ex. gut bacteria and decomposing bacteria
