Nitrogen Fixation
What does the chemical symbol "N" stand for?
Nitrogen
Ammonia converts to NO3 (which is what?)
Nitrate
NO3 and NH3 is absorbed by plants, which is then absorbed by what?
Anything above in the food chain (that is herbivorous)
What releases into the soil as organisms decay (that is a big part of this cycle?)
Ammonia, nitrogen also acceptable
NO3 reduces to N2 by what?
bacteria (anaerobic, cannot exist without oxygen, therefore often found in deep soil)
What is the chemical formula "NH3"?
Ammonia
Ammonia also converts to N2O (which is what?)
Nitrous Oxide
Negative, they contaminate groundwater and make it difficult for plants to absorb nitrogen.
What group of organisms break down dead decaying matter?
decomposers, ie bacteria, fungi, etc
What is the final step/product in denitrification?
N2
What does the chemical formula NO3 stand for?
Nitrate
What is the process in which NH4 turns into NO2 or NO3?
Oxidization
How does burning of fossil fuels affect the nitrogen cycle?
Burning of coal releases nitrogen oxides into air, creates smog worsens global warming in general.
What releases when inorganic nitrogen is broken down by organisms?
Ammonia
Where does this gas (N2) end up?
Back in the atmosphere/air
What organism breaks down nitrogen into nitrate?
Bacteria, prokaryotes, etc
What do cyanobacteria do in the process?
Take in oxygen for energy, convert nitrogen into ammonia or nitrate by combining
It is a major part of chlorophyll, which is a catalyst for photosynthesis.
What process releases organic nitrogen into the atmosphere?
Decaying organic matter
What organism performs nitrogen fixation?
Bacteria and some trees
What human actions create ammonia, which is horrible for the nitrogen cycle?
burning of fossil fuels, using fertilizer, etc
