Study Notes
Nitrogen Cycle Components
-
Nitrogen Fixation:
- Converts atmospheric nitrogen (N2) into ammonia (NH3).
- Occurs through the action of specific bacteria in legume roots or via lightning.
-
Nitrification:
- Process of converting ammonia (NH3) into nitrite (NO2-) and then into nitrate (NO3-).
- Performed by specialized bacteria, making nitrogen accessible to plants.
-
Assimilation:
- Involves the uptake of inorganic nitrogen (like NO3-) by plant roots.
- Transforms inorganic nitrogen into organic nitrogen, forming proteins and nucleic acids.
-
Ammonification:
- Converts organic nitrogen (from living organisms) back into ammonia (NH3).
- Carried out by decomposers such as bacteria and fungi, returning nitrogen to the soil.
-
Denitrification:
- Process where nitrates (NO3-) are converted back into atmospheric nitrogen (N2).
- Conducted by anaerobic bacteria, completing the nitrogen cycle.
Nitrogen Cycle Steps
- The nitrogen cycle consists of five key processes: Nitrogen fixation, Nitrification, Assimilation, Ammonification, and Denitrification.
