Though I would not call it food, any more than I would call oxygen food
for us, but the oxygen has to be taken in since it's not after the
nitrogen except for growth.

One more thing since you bring up human cellular respiration. We breath in
oxygen, do we "take it in"? Or do we use it for cellular repiration and
expell the oxygen in the form of CO2?

us (aerobic respiration)
C6H12O6 + 6O2 ---- 6CO2 + 6H2O (+ ENERGY (ATP)) -----NO
OXYGEN "taken in"

anaerobic denitrifying bacteria:

2NO3- + 12H+ ------- N2 + 6H2O + (ENERGY) -------NO
OXYGEN "taken in"

What do you think happens to the oxygen that is "removed" by the
bacteria?
That's its food.


This is a good one. You think oxygen is food for the ANAEROBIC
bacteria. Hmmm...
