Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that 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.
nitrogen fixation
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
through roots from the soil

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.
Plants use nitrogen in the form of nitrates. Nitrogen is essential in a healthy soil because plants use it in the form of an important nutrient.
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
Grass and plants use nitrogen to grow.
It allows plants to use nitrogen to grow.
nitrogen fixation
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
Bacteria and plant roots perform nitrogen fixation, which allows plants to use the nitrogen. Nitrogen is used in cells to build proteins and DNA. However, plants get their nitrogen as "nutrients" in the soil.
