New cards

Nitrogen Fixation

A process by which some organisms can convert nitrogen gas molecules directly into ammonia

3
New cards

Nitrification

The conversion of ammonia (NH4+) into nitrate (NO2-) and then into nitrate (NO3-)

4
New cards

Assimilation

The process by which producers incorporate elements into their tissues

5
New cards

Mineralization

The process by which fungal and bacterial decomposers break down the organic matter found in dead bodies and waste products and convert it into inorganic compounds

6
New cards

Ammonification

The process by which fungal and bacterial decomposers break down the organic nitrogen found in dead bodies and waste products and convert it into inorganic ammonium (NH4+)

7
New cards

Denitrification

The conversion of nitrate (NO3-) in a series of steps into the gases nitrous oxide (N2O) and, eventually, nitrogen gas (N2), which is emitted into the atmosphere
