6 terms · THE ACRONYM FIXation Ammonia Nitrification Nitrite/Nitrate Assimilation Proteins Ammonification Ammonium Dentrification Nitrogen

Abiotic Fixation

N₂ → NO
Nitrogen Gas → Nitrogen Monoxide
NO₂ → HNO₃
Nitrite → Nitric Acid
Lightning and Cosmic Radiation

Biotic Fixation

N₂ → NH₃
Nitrogen Gas → Ammonia

Soil Micro-organisms- Rhizobium bacteria and Legumes

Nitrification

NH₃ → NO₂⁻ → NO₃⁻
Ammonia → Nitrite → Nitrate

Micro-organisms- Nitrosomas (NO₂⁻) and Nitrobacter (NO₃⁻)

Assimilation

Nitrates to plant roots and then to other plants

Plants through root hairs

Ammonification

Nitrogenous waste and organic matter into inorganic ammonia

Decomposing micro-organisms like bacteria and fungi

Dentrification

Nitrates to gaseous nitrogen and lost to atmosphere

Facultative anaerobes
