Description
Nitrogen Cycle
1 78% Nitrogen gas in the atmosphere
2
3 Nitrogen is needed for making proteins for growth
4 - Plants get nitrogen from the soil
4.1 - Animals get nitrogen by eating plants
5 Nitrogen Fixation is the process of turning N2 from the air into Nitrogen compounds that plants can use
6 Decomposers - break down protein
6.1 Nitrifying Bacteria - turns ammonia into
nitrates in decaying matter
6.1.1 Nitrogen Fixing Bacteria - turn atmospheric N2
into nitrogen compounds that plants use
6.1.1.1 Denitrifying Bacteria - turns nitrates back into N2
gas. no benefit to living organisms.
7 There's so much energy in a lightning bolt that it's
enough to make nitrogen react with oxygen in the ait to
give nitrates
8 Nitrogen, just like carbon, is being
constantly recycled. So the nitrogen
in your proteins might once have
been in the air. And before that it
might have been in a plant. And
before that some horse wee. Nice.
