nitrogen cycle Flashcards
it is used in various things like
dna and rna
amino acids for proteins
how many % nitrogen gas are there in the atmosphere
78%
it break nitrogen gas apart and add hydrogen atoms to it
nitrogen-fixing bacteria
converts nitrogen gas from air into ammonia or ammonium in soil
nitrogen fixation
process where ammonia were taken by plants
assimilation
it is the conversion of ammonia to nitrates where the addition of oxygen to plants happen
nitrification
once the nitrogen is inside the plants it can passed other living things through
food webs and food chains
when the living things die and decompose the nitrogen returns back in the soil as ammonium
ammonification
it is the process where the nitrogen gas go back in the air
dentrification
they live in the root nodules of leguminous plants
rhizobium bacterium
process where nitrogen needs to get converted to nitrogenous compounds
nitrogen fixation
