Most Upvoted Answer
Explain nitrogen cycle with help of a diagram?
Nitrogen Cycle
- Nitrogen is an essential element for the growth and survival of all living organisms.
- However, nitrogen gas (N2) makes up 78% of the Earth's atmosphere and is not usable by most organisms.
- The nitrogen cycle is the process by which nitrogen is converted into various forms that can be used by living organisms.
Nitrogen Fixation
- Nitrogen fixation is the process by which nitrogen gas is converted into ammonia (NH3) by nitrogen-fixing bacteria.
- Some plants, such as legumes, have symbiotic relationships with nitrogen-fixing bacteria and can use the ammonia produced by the bacteria.
- Other bacteria can also perform nitrogen fixation in soil or water.
Nitrification
- Nitrification is the process by which ammonia is converted into nitrite (NO2-) and then into nitrate (NO3-) by nitrifying bacteria.
- Nitrate is the most common form of nitrogen used by plants.
Assimilation
- Assimilation is the process by which plants and animals take up nitrogen from the environment and incorporate it into organic molecules such as amino acids and nucleotides.
- Most plants take up nitrate ions from the soil through their roots.
- Animals obtain nitrogen by consuming plants or other animals.
Ammonification
- Ammonification is the process by which organic nitrogen compounds are broken down into ammonia by decomposers such as bacteria and fungi.
- The ammonia produced by ammonification can then be used in the nitrogen fixation and nitrification processes.
Denitrification
- Denitrification is the process by which nitrate is converted back into nitrogen gas by denitrifying bacteria.
- This process occurs in anaerobic conditions, such as in soil or waterlogged environments.
- Denitrification reduces the amount of available nitrogen in the environment and returns it to the atmosphere.
Overall, the nitrogen cycle is a complex process that involves a variety of biological and chemical reactions. It is essential for the proper functioning of ecosystems and the survival of living organisms.
