This is fixing atmospheric nitrogen as NH4+ or NO3-. This can be done industrially or naturally.
It is performed by nitrogen fixing bacteria that live on the roots of plants.
it helps by replenishing soil with nitrogen. Ex.- Rhizobium
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
Nitrogen fixation occurs in leguminous plant that have nitrogen fixing bacteria in the root nodule. The plants utilize the nitrogen from the nitrogen fixing bacteria. The bacteria utilize plant sugars formed via photosynthesis.
Nitrogen fixation. It can only be performed by a very small number of species of anaerobic bacteria.
It is usually performed by soil-living bacteria, such as nitrobacter.

Denitrification is a microbially facilitated process of nitrate reduction (performed by a large group of heterotrophic facultative anaerobic bacteria) that may ultimately produce molecular nitrogen (N2) through a series of intermediate gaseous nitrogen oxide products.
Nitrogen fixation as performed by a very few species of anaerobic soil bacteria. The most prolific species of these bacteria are symbiotic with legume plants. In the early 1900s Haber in Germany invented an industrial process to perform nitrogen fixation without the need for such microorganisms.
Nitrogen is a gaseous element, that is, what is in nitrogen is nitrogen.
The conversion of ammonia into nitrates is performed primarily by soil-living bacteria plus other nitrifying bacteria. The primary stage of nitrification, the oxidation of ammonia is performed by bacteria such as... Nitrosomonas species, which converts ammonia to nitrites.
