The nitrogen cycle. The nitrogen cycle shows how nitrogen is recycled in ecosystems; Plants and animals require nitrogen in order to produce proteins and nucleic acids (DNA and RNA); About 78% of the atmosphere is actually nitrogen gas but plants and animals cannot access the nitrogen in this gaseous form. Instead, they rely on certain bacteria to …
Nitrogen Cycle
1) Nitrogen fixation. Atmospheric nitrogen (N 2) is converted to ammonia (NH 3) by nitrogen-fixing bacteria in the soil. Bacteria (e.g. Rhizobia) form a mutualistic relationship with leguminous plants by inhabiting their root nodules. Leguminous plants (e.g. alfalfa, peas, beans) are a family of plants. The bacteria provide a source of ammonium ...

Nitrogen Cycle | Components, Process, Role, The Cyclic Path
During the nitrogen cycle, nitrogen flows through several compounds before it is added back to the atmosphere. A brief detail of all these processes is discussed below. Nitrogen Fixation. Nitrogen in gaseous form cannot be used by living organisms. It must be first converted into useable forms to begin the nitrogen cycle.
The nitrogen cycle (article) | Khan Academy
The nitrogen cycle is the cyclic movement of nitrogen in different chemical forms between living organisms and the environment. The steps of the nitrogen cycle are described below. Nitrogen fixation: During this step, atmospheric nitrogen gas is fixed, or converted into a form that can be used by plants and animals.
