Enviromental science 1.5 The Nitrogen Cycle

IM PASSING

nitogen fixation

process when nitrogen is taken from its molecular form(Ns) in the atmosphere and converted into nitrogen compounds useful for biochemical processes.

nitrogen fixing bacteria

bacterial process where molecular N2 gas is the converted to reactive, biologically available forms of nitrogen

Denitification

loss or removal of nitrogen gas by soil microbes

ammonificantion

step where death has occurred and material is converted into ammonium

assimilation

process when plants and animals incorporate NO3 and ammonia formed through nitrogen fix and nitritre

nitrification

when reduced nitrogen compounds are oxidized to nitrate and nitrite

nitrates

form of nitrogen, compound that naturally occures, air, soil, water, food sources includes ammonia, nitrates and nitrites

nitrites

intermediate compound involved in nitrification and denitrification.
