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.
Nitrogen gas, N2, is relatively inert and difficult to process. Only lightning and certain bacteria can convert it into usable forms.
Because they do not get enough of it.....
Heterotrophs get nitrogen from the food they consume in autotrophs like plants to get nitrate salts contained in the plants.
It's nitrogen fission of course
Nitrogen-Fixing bacteria. aka Rhizobium
Nitrogen- fixing bacteria consume nitrogen in the air and change it into a for that plants can use.
Plants transfer nitrogen in the nitrogen cycle through assimilation.

Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
Carnivorous plants must rely on insects for nitrogen since they are found in soils with low nitrogen levels. Since the soil can't provide them with enough nitrogen, they must consume insects to meet their nitrogen requirements.
trees do not give nitrogen..... nitrogen is a constituent of proteins, and plants do not consume proteins. also, there is no metabolic activity taking place in plants, so no nitrogen produced by plants.... it gives oxygen during photosynthesis, and carbon di oxide during respiration.. that's it....
Nitrogen-Fixing bacteria. aka Rhizobium
A lot of comes from the air. The air you breathe is around 78 percent nitrogen, so nitrogen enters your body with every breath. Rhizobium bacteria is present in leguminous plants in their roots which extract nitrogen from the soil. These are generally present in dicot-seed plants. When you consume these plants, nitrogen enters your body. Another way that nitrogen enters the body is through eating meat. When animals eat plants, those plants have nitrate in them which contains nitrogen so the animals have nitrogen in them now. Then, humans eat the meat from the animals, adding some nitrogen to our bodies.

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.
No,plants need nitrogen.
