What are two ways nitrogen from the air can change into usable nitrogen?

The nitrogen in the air can be used by the leguminous plants and can combine with the atmospheric oxygen.


What is the process of making nitrogen in the air usable to the plant is called nitrogen?

Nitrogen fixation :)


How do microorganism make nitrogen in the atmosphere usable to plant?

by nitrification of free nitrogen from the air


Why is the nitrogen in the air unusable to humans and other organisms?

Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil cuz bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria a.k.a. blue-green algae transform the nitrogen from the atmosphere into usable forms of nitrate


Name three ways plants get there nitrogen?

There are a great many ways in which a plant can get nitrogen. A plant can absorb nitrogen from the air.


Why can't plants and animals use nitrogen in the air?

plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.


Why do animals not obtain nitrogen from the air?

Nitrogen gas is fairly inert and so is difficult for organisms to process. Instead, animals must get usable nitrogen compounds from their food.


Why can't organisms use free nitrogen directly from the atmosphere?

Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil because bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria (a.k.a. blue-green algae) transform the nitrogen from the atmosphere into usable forms of nitrate


Does plants take in nitrogen directly from air?

NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.


Why don't plants get nitrogen from the air?

Nitrogen gas, N2, is relatively inert and difficult to process. Only lightning and certain bacteria can convert it into usable forms.


Nitrogen fixation is carried out primarily by?

Nitrogen-fixating prokaryotes (such as bacteria) present in the roots of legumes and some other plants take N2 from the air and convert it to nitrogen compounds usable by plants. Nitrogen fixing bacteria (diazotrophs).


How is nitrogen gas changed into liquid nitrogen?

Nitrogen becomes a liquid when it is cooled to below -196 °C (-321 °F). (The industrial production is by liquefying air, then separating the nitrogen.)


Can air be changed?

air can be changed if their is enough gas to change it also the air a long time ago was mainly hydrogen and helium now it is mainly oxygen, carbon dioxid nitrogen


What are different ways by which nitrogen in the air reaches the soil?

Most atmospheric nitrogen (N) exists as N2. Plants cannot use N in this form. The main ways this nitrogen enters soil in a plant usable form include:N fixation by bacteriaLightening caused atmospheric fixationFertilizer manufacturers also use atmospheric N when making N fertilizers.Most of the N is fixated by bacteria, usually in association with a plant. Legumes, like beans, peas and clover, are especially famous for this. The plants provide the bacteria with food and an environment they can live in, and in exchange, they give the plant usable nitrogen compounds.


What are Three ways that nitrogen is put into the soil so it can be used?

Nitrogen is put into the soil by the air having nitrogen naturally in it, animals waste, and the plants put nitrogen in the soil


How do bacteria help organisms use nitrogen?

Simply put, nitrogen from the air that enters the soil is a triple bonded diatomic atom. Bacteria can break this triple bond, even though plants can not. This puts the nitrogen into usable form for the plant.


What are the different ways by nitrogen in the air reaches the soil?

Nitrogen can enter the soil from plants such as legumes which fix nitrogen in their roots. Also dead plants and animals add nitrogen into the soil.


Which gas is produced during lightning?

The answer is (ii) Nitrogen dioxide. Nitrogen is available in air in bonded form N2. Lightning energy helps break this N2 bond and produces nitrogen ions. These ions combine with Oxygen to produce Nitrogen monoxide in the first step and then nitrogen dioxide. If there happens to be rain at the time of lightning, this NO2 dissolves in water to form nitric or nitrous acids and falls to earth. These acids are in usable form for many plants. This process is one of the ways for nitrogen fixation in the environment. Kalra


Does nitrogen contain air?

Nitrogen doesn't contain air, but the air contains Nitrogen.


How do organisms receive nitrogen?

Organisms receive nitrogen in several ways. About 78% the air we breathe containes nitrogen gas. Nitrogen is also in muscle and in nucleic acids, so anytype of food contains nitrogen atoms.


What things produce air?

Air is a mixture of components (such as oxygen, nitrogen, carbon dioxide, etc.) which can be created by many ways


What are the different ways by which nitrogen in the air reaches the soil?

Lightning changes the nitrogen in the air into another form called nitrate.THE NITRATE IS BROUGHT DOWN TO THE SOIL BY RAIN.Nitrate is the only form of nitrogen that can be absorbed by plants through its roots.--hhahahah


How do plants put nitrogen into the soil?

There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.


What percentage of nitrogen is their in your air?

About 78% of air is Nitrogen.


Is nitrogen in air?

Yes. About 75% of air is Nitrogen.
