Nitrification
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
Fixation
The role of bacteria in the Nitrogen Cycle is to perform biological nitrogen fixation. This process is an important part of the Nitrogen Cycle because it converts oxygen into ammonia that plants are then able to use.
Nitrogen-Fixing bacteria. aka Rhizobium
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
they get threw their roots and it is called nitrogen fixation

The reduction of nitrate to gaseous nitrogen. Most plants cannot use atmospheric(gaseous) nitrogen. It must be "fixed" by bacteria in the ground. Plants use nitrogen in the forms of ammonia(NH4+) and nitrate ions(NO3-). source: http://ohioline.osu.edu/aex-fact/0463.html
Nitrogen is considered to be a limiting factor for plants since it cannot be absorbed as a gas. Plants will use ammonia as their main source fro nitrogen.
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
Because it converts nitrogen into a form plants can use.
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
