Where d oes notrogen come from?

Answer 1

Nitrogen primarily comes from the Earth's atmosphere, which is composed of about 78% nitrogen gas (N₂). It is also found in the soil, where it is a key component of organic matter and is released through the decomposition of plants and animals. Additionally, nitrogen can be fixed from the atmosphere by certain bacteria and plants, converting it into forms that are usable by living organisms, such as ammonia and nitrates. Industrial processes, such as the Haber-Bosch process, also synthesize nitrogen compounds for fertilizers.
