The nitrogen cycle is the process by which nitrogen is converted from ... Nitrogen
is converted from atmospheric nitrogen (N2) into usable forms, such as ... to use
atmospheric nitrogen (N2), it must be "fixed" or converted into ammonia (NH3). ...
This is important because plants can assimilate nitrate into their tissues, and ...
Nitrogen in the gaseous form cannot be absorbed and used as a nutrient by
plants and ... Plants can use ammonia as a nitrogen source. ... anaerobic bacteria
will convert them back into nitrogen gas, during a process called denitrification.
If nitrogen in the atmosphere is not in a form plants can use how do they get
nitrogen what is this process called? they get threw their roots and it is called ...
Nitrogen fixation is the process wherein N2 is converted to ammonium, or NH4<sup>+</sup>.
... Once in the form of ammonium, nitrogen is available for use by plants or for
further ... Eventually, this atmospheric nitrogen can be blown into nitrogen-
These organisms convert nitrogen in the soil to ammonia, which can then be
taken up by ... After nitrogen has been fixed, other bacteria convert it into nitrate,
in a process ... Plants cannot use the nitrogen in our atmosphere without the
assistance of ... Plant roots assimilate Nitrogen mainly in the form of nitrates while
Plants normally use nitrogen in only the ammonium and nitrate forms. ... it
through the processes of fixation, mineralization, nitrification, leaching, plant
assimilation, ... Bacteria can convert nitrogen to organic forms through fixation. ....
