Plants can get nitrogen from some of fertiliser
yes
78% of the air in Earth's atmosphere is nitrogen. Also, all plants have nitrogen.
Because they don't want to.
Bacteria is the the most responsible organism that converts nitrogen into nitrates. Which plants can then use.
The atmosphere (air) and through the nutrients in the soil.
Yes. Vascular plants can absorb nitrogen compounds such as nitrates from the soil on their own.What plants can't do on their own is fix nitrogen from the air into nitrogen compounds. Some plants including legumes (such as peas, beans, lupins) and casuarinas form symbioses with nitrogen-fixing bacteria to form nitrogen into nitrogen compounds.
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
plants take in nitrogen compounds through their roots.
It is performed by nitrogen fixing bacteria that live on the roots of plants.
Plants which aid in replenishing nitrogen in agricultural lands are called "nitrogen fixing" plants. Most of these actually host a bacteria in the roots of the plant that actually converts nitrogen to a formulation that can be used by plants. This is then stored in the roots as nodules. Most legumes are considered Nitrogen fixing although the most commonly used for this purpose is Clover.
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
From plants or air.
The use of nitrogen and other fertilizers will enhance the growth of most plants when used correctly.
it is the part of the nitrogen cycle

they get it from the soil.
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).
