The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted
into various chemical forms as it circulates among the atmosphere and terrestrial
and marine ecosystems. The conversion ...
If nitrogen in the atmosphere is not in a form plants can use how do they get

conversion is called nitrogen fixation, and makes the nitrogen ... Nitrogen-fixing
bacteria ... Plants can not use N2, and the N2 can therefore escape into the
The nitrogen cycle is split up into five main processes. ... Nitrogen gas cannot be
directly used by plants and therefore needs to be converted into nitrate
