- bacteria, 2. archaea 3. eukaryea
inhabit soil, surface waters, and the tissues of other living or decaying organisms
bacteria
inhabit extreme enviroments
archaea
all eukaryotic organisms
eukarya
Plentiful supply of O2, organisms transfer electrons from fuel to o2 for energy
aerobic
devoid of O2, organisms transfer electrons to nitrate sulfate, or CO2 for energy
anaerobic
die when exposed to O2
obligate anaerobes
can live wit her without O2
facultative anaerobes
composed of plasma membrane, outer membrane, and peptidoglycan
cell envelopec
cell envelope function
increases rigidity
