Which organisms can use nitrogen directly from the atmosphere?

Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby breaking the tough triple bond of molecular nitrogen. Such organisms are called “diazotrophs”.

Can organisms use nitrogen from the atmosphere?

All living things need nitrogen to build proteins and other important body chemicals. However, most organisms, including plants, animals and fungi, cannot get the nitrogen they need from the atmospheric supply. They can use only the nitrogen that is already in compound form.

How do humans get nitrogen?

The most common way for people to get nitrogen into their bodies is through eating when their water supply contains less than 10 mg of nitrate per liter. When the levels of nitrate are above 50 mg, then the water supply becomes the main source of intake for people to get nitrogen into their bodies.

Does human body need nitrogen?
