What is the process by which bacteria convert nitrogen to ammonia?

This process is called the Nitrogen Cycle. Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.
A.

What are the 5 steps of nitrogen cycle?

In general, the nitrogen cycle has five steps:
  • Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
  • Nitrification (NH3 to NO3-)
  • Assimilation (Incorporation of NH3 and NO3- into biological tissues)
  • Ammonification (organic nitrogen compounds to NH3)
  • Denitrification(NO3- to N2)
  • How does nitrogen cycle?

    This process is called the Nitrogen Cycle. Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.
  • What is nitrogen cycle explain it?

    The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among the atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
  • How do animals get the nitrogen they need?

    Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
B.

How is nitrogen converted into a usable form?

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
  • Where do plants get nitrogen from?

    Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots.
  • What is the use of nitrogen?

    Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
