Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert atmospheric nitrogen into compounds like ammonia that can be used by plants. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available in a form that other organisms can use for growth.
The process that converts nitrogen compounds into ammonia is called nitrogen fixation. Microorganisms such as certain bacteria and archaea, as well as lightning and industrial processes, can carry out nitrogen fixation.
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
Bacteria utilize an enzyme called nitrogenase to convert nitrogen gas (N2) into ammonia (NH3) in a process known as nitrogen fixation. This ammonia can then be further converted into other nitrogen compounds by bacteria to be used by plants and other organisms.
ammonia
Some bacteria have the ability to "fix" nitrogen, that is they can utilize gaseous (atmospheric) nitrogen to produce organic compounds. (They can all break down compounds to free nitrogen too.)
They are called nitryfying bacteria. Examples are Rhizobium, Anabena etc
The process that converts nitrogen compounds into ammonia is called nitrogen fixation. Microorganisms such as certain bacteria and archaea, as well as lightning and industrial processes, can carry out nitrogen fixation.
The term for bacteria that convert atmospheric nitrogen into nitrogen compounds is "nitrogen-fixing bacteria." These bacteria, such as those in the genera Rhizobium and Azotobacter, play a crucial role in the nitrogen cycle by transforming nitrogen gas (N₂) into forms that plants can utilize, like ammonia (NH₃). This process is essential for soil fertility and agricultural productivity.
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
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
Nitrogen fixation.
I have no idea what the answer is.
Chemoautotrophs like Nitrogen fixing bacteria
The bacteria that converts nitrogen gas into ammonia is known as nitrogen-fixing bacteria. Some examples of nitrogen-fixing bacteria include Rhizobium, Azotobacter, and Clostridium. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available to plants.
bacteria in root fixes free nitrogen ito simple compounds
Nitrogen fixing bacteria, such as Rhizobium.
Nitrogen fixation occurs in1 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. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
