Nitrogen Cycle Definition

Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria.

Nitrogen cycle definition. The nitrogen cycle is vital for life on Earth. The nitrogen cycle is the circulation of nitrogen in various forms through nature. This process is performed by the anaerobic bacteria.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere terrestrial and marine ecosystems. Follow nitrogen and phosphorus cycles and learn why farmers fertilize fields after harvest. In general the N cycle processes.

The series of processes by which nitrogen and its different forms are circulated and interconverted in nature with the help of living organisms is called the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes which convert atmospheric nitrogen text N_2 N2 into biologically usable forms in a process called nitrogen fixation.

The nitrogen cycle is the recycling phase of the nitrogen which includes nitrogen fixation ammonification nitrification and denitrification. Processes in the Nitrogen Cycle Fixation - Fixation is the first step in the process of making nitrogen usable by plants. Nitrogen fixation nitrification and denitrification.

Nitrogen cycle - the circulation of nitrogen. It shows the path that nitrogen follows through the biogeochemical cycle using its storage reservoirs such as the atmosphere living organisms and soil. Denitrification is the process through which the nitrates and nitrites are converted back to atmospheric nitrogen.

Here bacteria change nitrogen into ammonium. The cycle where nitrogen is used by a living organism then after the organism dies is restored to soil followed by its final conversionto its original state of oxidation. Nitrogen cycle - definition.
