Any legume will convert nitrogen to nitrates, as well as many bacteria found in the soil
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
Legumes (e.g peas and beans). They form symbiotic relationships with Rhizobia bacteria which fix atmospheric nitrogen into nitrates which can be used by the plant.
Nitrogen. Bacteria can convert or "fix" insoluable Nitrites into soluable Nitrates, which plants can absorb
Autotrophs get the nitrogen from the soil by the nitrogen fixing bacteria that convert nitrogen to nitrate salts used up by plants while heterotrophs gets them when they consume the autotrophs, making them have some of the nitrates in palnts. Autotrophs and heterotrophs then die and are decomposed by bacteria to recycle the nitrogen in air . Some of those bacteria converts the nitrates into form of nitrogen recycling them into the atmosphere.

Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
Nitrifying bacteria converts ammonia compounds into nitrites and nitrates while denitrifying converts the nitrates into atmospheric nitrogen gas. It is confusing as at first I thought that the denitrifying bacteria would convert the nitrates into ammonia, but that is wrong. Denitrification is the opposite to nitrogen fixation, not nitrification.
Humans use nitrogen in the form of proteins. Bacteria found in soil convert atmospheric nitrogen into nitrates that plants use to produce proteins.

Conversion of Nitrogen gas into Nitrates\Ammonia.-When Lightning strikes the nitrogen in air get converted into Nitrogen Oxides and then is brought down by rain in from of Soluble Nitrates.These Nitrates are the soluble form of nitrogen for plants. Though lightning play a minor role in nitrogen fixation.-Nitrogen is also fixed by Microorganisms which are free-living or the organisms that live in the plants (Symbiotic relations).These Organisms convert the nitrogen in soluble nitrates.-Nitrogenous Fertilizers are also one from of Soluble nitrogen.*** These Nitrates and ammonia fertilizers are then consumed by plants and the plants are consumed by us.Hence Nitrogen is in the Biotic Part of the Ecosystem.

Many species of soil bacteria fix nitrogen,that is, they convert it into compounds that are readily absorbed by plants.
