What organisms are necessary for producing ammonia nitrates and nitrites during the nitrogen cycle?
A type of anaerobic bacteria called nitrogen fixing bacteria.
What is denitifying bacteria?
This is a misprint of 'denitrifying'. Denitrifying bacteria are commonly present in anaerobic environments, both in ocean sediments and freshwaters. They are responsible for the reduction of inorganic nitrogen compounds (nitrates NO3-) to gaseous nitrogen (NO, N2O and N2) and may be the source of all nitrogen gas in the atmosphere.
Where does nitrogen in the soil come from?
Nitrogen compounds known as Nitrates found in the soil
The conversion of nitrates to nitrogen gas by bacteria is called?
Nitrogen Fixation.
What is the role of autotrophs and heterotrophs in the cycling of nitrogen through the environment?
Autotrophs get the nitrogen from the soil by the nitrogen fixing bacteria that convert nitrogen to nitrate salts used up by plants while heterotrophs gets them when they consume the autotrophs, making them have some of the nitrates in palnts. Autotrophs and heterotrophs then die and are decomposed by bacteria to recycle the nitrogen in air . Some of those bacteria converts the nitrates into form of nitrogen recycling them into the atmosphere.

What would happen if the bacteria that cause denitrification were removed from the nitrogen cycle?
denitrification is soil bacteria converting nitrates into nitrogen gas, is process releases nitrogen into the atmosphere. If there wasn't any bacteria, there would be no process and therefor the nitrogen wouldn't make it into the atmosphere.
How do nitrates produced?
in nature nitrogen from the atmosphere is converted to ammonia by nitrifying bacteria ammonia is then converted to nitrite and then to nitrate by nitrogen fixing bacteria. nitrate is converted back to nitrogen by denitrifying bacteria
How is nitrogen returned to the atmosphere?
Nitrogen return to the atmosphere by the process of Denitrification. Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such asPseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.

What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
What plant will convert nitrogen into nitrates?
Any legume will convert nitrogen to nitrates, as well as many bacteria found in the soil
What organism is responsible for converting nitrogen into nitrates?
Bacteria is the the most responsible organism that converts nitrogen into nitrates. Which plants can then use.
What converts nitrogen in the nitrogen cycle?
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
