The nitrogen song

http://new.music.yahoo.com/amy-bronson/tracks/nitrogen-cycle-song--218107710



nitrogen composes 79% of our atmosphere
and nitrogen is very important for sustaining life here.
Let me tell you a little story about
nitrogen fixation.
Well lightning struck, and N2s joined with O2s to make nitrates and the little NO3s dissolved into rain and fell down to the ground to be absorbed by trees so proteins could be produced.
Then an animal ate some of the trees leaves for protein
to survive, until it died, boo hoo
and decomposed into
ammonia, then nitrites, then nitrates
with a little bit of it turned back into nitrogen gas
by denitrifying bacteria for the sake of balance.
Then a human ate some of the trees leaves so it could have protein, too, but it didn’t die, no, it just peed
in woods, oo,
but that’s alright because urine contains urea which is
ammonia which turns into nitrites and then nitrates
with a little bit of it turned back into nitrogen gas
by denitrifying bacteria for the sake of balance, hey balance, hey balance.
Well, lightning’s not the only way for nitrogen to fixate, that is, to turn into nitrates,
ask any vegetarian and they will tell you that legumes are an important source of protein but why?
Well in the roots of these legumes live
tiny nitrogen fixating bacteria and they too
can make O2s join with N2s to make nitrates
and the little NO3s dissolve into rain and fall down to the ground to be absorbed by trees so proteins can be produced
and the animals and the people can eat them and pee
and die and decompose into
ammonia, then nitrites, then nitrates with a little bit of it turned back into nitrogen gas by denitrifying bacteria for the sake of balance, hey balance, hey balance.
And this is a cycle so it happens over and over and this song’s over, it’s over, it’s over.
The End.
