Nitrogen fixation occurs in
1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,
2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium
3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.

What organisms convert nitrogen into a form that is usable by humans?
Bacteria Ammonia, nitrates, nitrites
Why are bacteria important to the nitrogen cycle?
because when bacteria convert ammonia into nitrates and nitrites, producers need them to make proteins, and then consumers eat the producers and reuse the nitrogen to make their own proteins.
Living organisms require nitrogen to make nitrates and nitrites which are used to build?
proteins
What is the end product of nitrate metabolism?
There is no end product of nitrate metabolism. Nitrates, themselves, are one of the end products of protein metabolism. Nitrite resulting from nitrate might confuse some people into thinking that there is nitrate metabolism. In the case of a UTI caused by bacteria, the bacteria produce an enzyme that changes urinary nitrates to nitrites, but this is not metabolism. It's the result of an enzymatic action.
Heat nitrates what happen?
If the nitrates are of alkali metals, they decompose into Nitrites and Oxygen:NO3- --Δ--> NO2-+ O2If the nitrates are of other metals, they decompose into Metal oxides, Nitrogen dioxide and Oxygen:NO3- --Δ--> O2- + NO2 + O2
What organisms convert nitrogen into a form that is by humans?
Bacteria Ammonia, nitrates, nitrites
What organisms convert nitrogen into a form that is usable by humans?

What are salts that are converted to nitrites by bacteria?
Nitrates
What dangers do high level nitrates in the drinking water present for infants?
Humans and other animals usually have bacteria that convert nitrates into nitrates in their large intestines. For adults, the presence of these bacteria in the digestive system is not harmful, because the stomach of an adult is so acidic that the bacteria cannot survive. But the stomach of an infant is much less acidic, so the bacteria can move up into the stomach, where they will convert nitrates into nitrites. The nitrites can then pass into the blood of the infant.

Plants need bacteria in order to take up and use which element?
Nitrogen. Bacteria can convert or "fix" insoluable Nitrites into soluable Nitrates, which plants can absorb
How can N be removed from wastewater treatment?
Nitrobacter play an essential role in aquaponics. Nitrosomonas bacteria first convert ammonia into nitrites. Nitrobacter convert the nitrites into nitrates, which are readily absorbed by the plants. Read more at the link below.
What causes nitrits in urine?
According to WebMD: Nitrites. Bacteria that cause a urinary tract infection (UTI) make an enzyme that changes urinary nitrates to nitrites. Nitrites in urine show a UTI is present.
What are three products of nitrogen fixation?
Ammonia, nitrates, nitrites
What bacteria is in nitrogen compounds?
Bacteria Certain bacteria can use nitrogen from the air to make nitrogen-containing substances called nitrites. Other bacteria can turn nitrites into nitrates-another group of nitrogen-containing substances.
Are bacteria that live in the root systems of legumes?
these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
What is the difference between Nitrosomonas and Nitrobacter?
Nitrosomonas convert ammonium compounds into nitrites. Nitrobacter converts these nitrites to nitrates. Both form a part of Nitrogen Cycle.
