Biology Nitrogen cycle + negative control

what is a negative control?

not to expect any reaction/ dependent variable

nitrogen fixation

Nitrogen gas is fixed into ammonia (NH3), later ionized to ammonium (NH4+) by getting hydrogen ions from the soil solution

nitrification

2-step process

NH3/NH4+ is converted to Nitrate (NO3)

assimilation

where plants and animals take up Nitrate(NO3) and ammonium (NH4) to incorporate them into organic molecules (proteins, amino acids, nucleic acids)

ammonification

when both plants and animals decompose (died), releasing ammonium (NO3) into the soil

denitrification

when nitrate (NO3) is converted back into nitrogen gas (N2) back into the atmosphere
