Autotrophs
|
self-feeder-carbon dioxide converted into organic molecules
|
|
|
nitrogen sources
|
hetertrophs=food (proteins and nucleic acids)
|
|
|
oxygen sources
|
in organic molecules, inorganic salts, in the air
-essential for metabolism in many cells |
|
|
hydrogen source
|
organic and in organic molecules
necessary for pH, hydrogen bonds and redox reactions |
|
|
phosphorous sources
|
inorganic phosphates
may be limiting growth factor plants-absorb in roots hetertrophs from consumption |
|
|
sulfur sources
|
in nature in inorganic molecules
in AA cystiene and methionine -consume it |
|
|
K, Na, Ca, Mg, Fe, Zn
|
found in environment-organic and inorganic
|
|
|
Photoautotrophs
|
carbon source-CO2
energy source-light -plants, algae, a few protists |
|
|
chemoautotrophs
|
carbon source-CO2
energy source-inorganic molecules -lithoautotrophs |

carbon source-organic molecules
energy source-light -purple/green bacteria |
|
|
chemoheterotrophs
|
carbon source-organic molecules
energy source-organic molecules -animals, pathogens |
|
|
group translocation
|
molecule brought into cell and changed into useable form at same time-may involve addition of other atoms/functional groups
