I'd really appreciate some help in Bio regarding teeth ( mainly cross section and internal structure) and the nitrogen cycle...Ive always been confused cuz theres so many different bacteria involved....and how nitrates are being formed but CO2 is still being produced. Any help or even any notes...

I'm having trouble too, especially the structure of teeth, the dentine and enamel and everything, I can't seem to find a proper set of notes for it online.
