nitrogen cycle
a place where anything is stored
what is Reservoir
it where plants combine nitrogen and hydrogen to form ammonia
what is Industrial fixation
process when plants take up wh4
what is assimilation
lives in deep swampy sediments where oxygen is not easily found
what is Denitrification
three ways to fix nitrogen
what is atmospheric fixation
what is industrial fixation
what is biological fixation
a series of actions that produce something
what is process
highly specialized bacteria that lives in soil
what is biological fixation
when a plant or animal dies or leaves waste products like fungi and bacteria turn N2 into ammonia
what is ammonification
can lead to cancer in humans
what is N2
what is atmospheric nitrogen
makes up 78% of earths atmosphere
fixes 30% of available N2
what is bacteria
cause of nitrogen fertilizers
what is human impact
can lead to nutrient over enrichment
what is groundwater
what is N2o
what is nitrous oxide
process where molecules in the air break apart
what is Nitrogen fixation
process where N2 molecules break apart
what is lightning
allows invasion by non native plants into ecosystems
what is excess nitrogen
it is used as fertilizer
what is ammonia
what is nh4
what is ammonia
energy from lightning breaks molecules apart
what is atmospheric fixation
bacteria in the ground that combines with ammonia
what is Nitrification
is the result of nitrogen fixation
what is plants nutrients
carried to the ground by rain
what is no2
