The nitrogen cycle is ongoing and does not have a fixed duration. It is a continuous process in which nitrogen is converted between various forms by different microorganisms in the environment. The cycle involves steps such as nitrogen fixation, nitrification, assimilation, and denitrification, all of which occur at different rates and time frames depending on the environment and conditions.
Evaporation: Heat from the sun causes water from the ocean to evaporate into the atmosphere. Condensation: The water vapor in the atmosphere cools and condenses into clouds. Precipitation: When the clouds become saturated with water droplets, precipitation occurs in the form of rain.
The nitrogen cycle is generally considered a slow process. It involves various steps, including nitrogen fixation, nitrification, and denitrification, which can take place over weeks to years. While some aspects, like nitrification, can occur relatively quickly, the overall cycle is prolonged due to the complex interactions between soil, organisms, and atmospheric nitrogen. Thus, while certain processes can be fast, the complete cycle is typically slow.
N2 molecules break apart via nitrogen-fixing bacteria. Other living entities such as plants and animals ingest nitrogen in nitrate-containing compounds. Organic matter decays via decomposers. N2 is formed via denitrifying bacteria.

nitrogen fixation, denitrification, nitrification, amonification are the for steps of the nitrogen cycle.
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
N2 molecules break apart via nitrogen-fixing bacteria. Animals ingest nitrogen in nitrate-containing food after plants use nitrogen containing compounds. Organic matter decays via decomposers. N2 is formed via denitrifying bacteria.
Nitrogen fixation is the process where nitrogen gas in the atmosphere is converted into a form that organisms can use. Nitrification involves the conversion of ammonium to nitrate by bacteria. Assimilation is the process by which plants and animals incorporate nitrate and ammonium into their tissues. Ammonification is the breakdown of organic nitrogen into ammonium by decomposers. Denitrification is the process by which nitrogen in the form of nitrate is converted back into nitrogen gas by bacteria.
The nitrogen cycle is the process by which nitrogen is converted and circulated in the environment. It involves several steps: nitrogen fixation, nitrification, assimilation, ammonification, and denitrification. In simple terms, nitrogen gas in the atmosphere is converted by bacteria into a form that plants can use. Plants then absorb this nitrogen to grow. When plants and animals die, bacteria break down their organic matter, releasing nitrogen back into the soil. This nitrogen can then be used by plants again, completing the cycle.
The nitrogen cycle involves several key steps: nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium to nitrite, and then nitrate by bacteria), assimilation (incorporation of nitrogen into plant and animal tissues), ammonification (conversion of organic nitrogen into ammonium), and denitrification (conversion of nitrate back into atmospheric nitrogen by bacteria). These processes help maintain a balance of nitrogen in ecosystems.
Daniel Rutherford discovered nitrogen in 1772; Antoine Lavoisier was the first to consider nitrogen as a chemical element.
