The Basic Calibration Process is the process through which an instrument is calibrated, or set to a scale, during its manufacturing process - and it must be able to "hold a calibration."
compound
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
"fixation" (usually turning into ammonia)
Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
through roots from the soil
Nitrogen must be in the compound form before it is used by plants or animals
An estate must go through the probate process before being settled to ensure that all relevant taxes and fees due are paid. Once this has happened the estate can be settled and distributed as stipulated in a will.

Nitrogen gas is fairly inert and so is difficult for organisms to process. Instead, animals must get usable nitrogen compounds from their food.
Nitrogen has 3 isotopes. All of them have 7 protons. (That's why they're nitrogen.) Let's look at the isotopes. 13N - Nitrogen with 6 neutrons 14N - Nitrogen with 7 neutrons 15N - Nitrogen with 8 neutrons The first isotope is a synthetic one. It must be made through a nuclear process. The other two are naturally occurring isotopes. A link is provided to Wikipedia, which was the source for this information.

if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
