Jan 15, 2021 · Definition. The nitrogen cycle refers to the cycle of nitrogen atoms through the living and non-living systems of Earth. The nitrogen cycle is vital for life on Earth. Through the cycle, atmospheric nitrogen is converted to a form which plants can incorporate into new proteins.

Nitrogen Cycle Definition. “Nitrogen Cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.”. Furthermore, nitrogen is a key nutrient element for plants. However, the abundant nitrogen in the atmosphere cannot be used directly by plants or animals.

- Nitrifying bacteria are a small group of aerobic bacteria, which are mainly involved in the conversion of ammonia into nitrates.
- The process of nitrogen fixation is carried out naturally in the soil within nodules in the plant’s root systems.
Feb 25, 2020 · The entire process of the Nitrogen Cycle, one of the important biogeochemical cycle takes place in five stages: 1) Nitrogen Fixation by Bacteria – Converting inert atmospheric nitrogen (N 2)into biologically available forms such as ammonia (NH 3), nitrates, or nitrites. 2) Nitrification by Bacteria – Converting ammonia to nitrite and then ...
The Haber process is arguably one of the most important human discoveries of all time. It is definitely the most important discovery in terms of the nitrogen cycle. This process synthesizes ammonia from air and methane. Fritz Haber and Carl Bosch discovered the technique in 1909.
Answer: The nitrogen cycle is the recycling phase of the nitrogen which includes nitrogen fixation, ammonification, nitrification, and denitrification. Denitrification is the process through which the nitrates and nitrites are converted back to atmospheric nitrogen. This process is performed by the anaerobic bacteria.

How does nitrogen follow through the biogeochemical cycle?
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation ...
