∙ 13y agoNitrogen occurs in nature in its gaseous form. It is 78% in our atmosphere as N2.
Also,it occurs in minerals in form of nitrates, nitrites, nitriles etc.

How chronic illnesses affect physical development?
Chronic illnesses can damage and stunt the normal peocesses that take place in the body in many ways. every thing from muscular atrophy to nerve damage.
What changes take place on the earth surface?
Volcanoes and earth slides are two ways that earth's surface change quickly.
How do you clear the error codes on a 2000 Honda Civic?
By taking the car somewhere to have the problem(s) fixed that are causing the codes. There are several ways. You can disconnect the battery, wait a little while and then reconnect it; take it to a place that has a code reader (like Autozone); turn the engine on and off several times. The main point is that if you haven't fixed what caused the light to come on, it will turn on again. If you take it to a place like Autozone, they will tell you what is causing it to turn on.
How do earthworms improve garden health?
The opening up of passageways through the soil and the leaving of nutrient rich organic matter are two ways in which earthworms improve garden health. The passages that they open in their movements through soil encourage the presence of air and water pore spaces. Pore spaces encourage appropriate levels of air and moisture below ground. They thereby discourage compaction and erosion.The matter that earthworms leave in soil comes in the form of droppings. These droppings are high in such important nutrients as nitrogen. Plants only can take nitrogen in soluble form. Nitrogen that otherwise is unavailable to plants becomes available once it passes through and out of earthworm.
How do you get more power up rewards points?

How is nitrogen fixation carried out?
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
What is economic important of fungi?
the economic important of a fungi is how they using asexual repruducing :)
What are some ways that bacteria can help the environment?
(i) De composer bacteria help in decomposing matter in the soil. (ii) It helps to maintain fertility in soil. (iii) Bacteria like cyanobacteria help in nitrogen fixation.
Is a bond between hydrogen and nitrogen a hydrogen bond?
It depends. In an individual molecule, covalent bonds hold the nitrogen atom to the hydrogen atom. This is a type of a intramolecular force and is responsible for holding the atoms in a molecule together. In a group of NH containing molecules, the force responsible for holding the molecules together is due to is the hydrogen bond. This is a intermolecular force and is responsible for holding the molecules together. So basically, if the hydrogen and nitrogen are in the same molecule it's not a hydrogen bond and if they're not in the same molecule and there's a still an attraction it is a hydrogen bond.
What is the process of changing atmospheric nitrogen into forms that plants can use is what?
The conversion of nitrogen (N2) from the atmosphere into a form readily available to plants and hence to animals is an important step in the nitrogen cycle, which distributes the supply of this essential nutrient. There are four ways to convert N2 (atmospheric nitrogen gas) into more chemically reactive forms:[5]Biological fixation: some symbiotic bacteria (most often associated with leguminous plants) and some free-living bacteria are able to fix nitrogen as organic nitrogen. An example of mutualistic nitrogen fixing bacteria are the Rhizobiumbacteria, which live in legume root nodules. These species are diazotrophs. An example of the free-living bacteria is Azotobacter.Industrial N-fixation: Under great pressure, at a temperature of 600 C, and with the use of an iron catalyst, hydrogen (usually derived from natural gas or petroleum) and atmospheric nitrogen can be combined to form ammonia (NH3) in the Haber-Bosch process which is used to make fertilizer and explosives.Combustion of fossil fuels: automobile engines and thermal power plants, which release various nitrogen oxides (NOx).Other processes: In addition, the formation of NO from N2 and O2 due to photons and especially lightning, can fix nitrogen.
How do plants and animals differ in the ways they obtain nitrogen?
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
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 two ways nitrogen from the air changed into usable nitrogen?
lightning & bacterial action (nitrogen fixers).
How has the element nitrogen helped humans?
Nitrogen help humans in diffrent ways
Why cant plants absorb gaseous nitrogen?
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.
What the processes involved in the nitrogen cycle?
plans take them both in and convert them both to a form we (and other animals) can use - sugars and proteins. decomposers are the type of bacteria that break dead things down - so convert the carbon in us to the CO2 form or into organic material in the soil and they also convert the nitrogen in living things into ammonium in the soil. the nitrogen fixing bacteria turn the nitrogen from the soil also into the ammonium. the ammonium is converted into nitrates by nitrifying bacteria which can be then used by plants and then we eat the plants...
