What is nitrogen used for in living organisms?
To manufacture proteins and nucleic acids
How is nitrogen taken up by a plant?
Nitrate ions (NO₃⁻) are absorbed using active transport by the root hairs. Animals take in nitrogen by eating and digesting plants.
What is the process of ammonification?
Ammonification --> Production of ammonia from organic ammonium-containing compounds (e.g. urea, proteins, nucleic acids and vitamins (found in faeces))

Saprobiotic microorganisms feed on these materials and release ammonia which then forms ammonium ions in the soil.
Where does nitrogen return to the non-living component of the ecosystem?
When bacteria feed on ammonium containing compounds such as faeces and release ammonium ions into the soil :)
What is converted to what in nitrification?
Ammonium ions into nitrate ions .
What is the name for the microorganisms that carry out nitrification?
Nitrifying bacteria
What are the two stages of nitrification?
Oxidation of ammonium ions to nitrite ions

Oxidation of nitrite ions to nitrate ions
For nitrification to occur...
...the soil needs to be well aerated and light
What is the process of nitrogen fixation?
When nitrogen gas is converted into nitrogen containing compounds
What are the two main types of nitrogen fixing bacteria?
Free-living NF bacteria

Mutualistic NF bacteria
Nitrogen fixation converts what to what?
Free living NF bacteria reduce gaseous nitrogen to ammonia, which they then use to manufacture amino acids

Mutualistic NF bacteria receive carbs from the plant and the plant acquires amino acids
What is the process of denitrification?
When soil nitrates are converted into gaseous nitrogen
