The two process are as follows
1.NITROGEN FIXATION
Nitrogen fixation is the process of converting the atmospheric nitrogen (N2) into biological state nitrogen. It is the first process of making nitrogen available for plants. It is defined as an anaerobic (without oxygen) process that catalyzes the reduction of atmospheric nitrogen (N2) into ammonia (NH3).
The process is solely carried out by prokaryotes (bacteria) which have the natural strength to break the triple bond between the nitrogen atoms. These nitrogen-fixing organisms are free-living bacteria whereas others are symbiotic nitrogen fixers. An example of a nitrogen fixer is the Rhizobium bacteria in the roots of legumes

Answer:
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
