| Question | Answer |
|---|---|
| Nitrogen Cycle | Fixation Ammonification Nitrification Assimilation Denitrification [Fruity African Negros Ate Dominos] |
| Fixation | Builiding NH₃ from gaseous N₂ via bacteria in the nodules of certain plants or lighting |
| Ammonification | Conversion of organic nitrogen compounds (like proteins and nucleic acids) into ammonia (NH₃) and ammonium ions ([NH₄]⁺) by decomposer microorganisms |
| Nitrification | Biological conversion of ammonia (NH₃) to nitrite (NO₂⁻) and then to nitrate (NO₃⁻) by specific bacteria |
| Assimilation | Inorganic NH₃ is built into organic compounds [amino acids] |
| Denitrification | Bacteria convert NO⁻ ₃ into N₂ |
