Question

plz explain nitrogen cycle in detail

plz use simple words

and plz don't copy the answer from the Google

Answer 1

circulation of nitrogen in various forms through nature. Nitrogen, a component of proteins and nucleic acids, is essential to life on Earth. Although 78 percent by volume of the atmosphere is nitrogen gas, this abundant reservoir exists in a form unusable by most organisms. Through a series of microbial transformations, however, nitrogen is made available to plants, which in turn ultimately sustain all animal life. The steps, which are not altogether sequential, fall into the following classifications: nitrogen fixation, nitrogen assimilation, ammonification, nitrification and denitrification.

Answer 2

The nitrogen cycle is the way that nitrogen in nature is changed into many different forms that are used by living organism[s].

Air is about 78% nitrogen. Nitrogen is needed for life. It is an important part of proteins, DNA, and RNA. In plants, nitrogen is needed for photosynthesis and growth. [1] Nitrogen fixation is needed to change the nitrogen in air (N2) into forms that can be used by life. Most nitrogen fixation is done by microorganisms called bacteria. These bacteria have an enzyme that combines N2 with hydrogen gas (H2) to make ammonia (NH3).

Some of these bacteria live in the roots of plants (mostly legumes). In these roots, they make ammonia for the plant and the plant gives them carbohydrates. Other plants take nitrogen compounds out of the soil through their roots. All nitrogen in animals comes from eating plants.

Ammonium (NH4) in soil is made by nitrogen-fixing bacteria and decomposers, bacteria and fungi that break down dead life into its parts. This process is called ammonification. Ammonium has a positive charge. It easily joins to clay and humus in the soil. Ammonia and ammonium are poisonous to fish and other animals. Sewage and other waste-water is regularly measured because of this. If ammonia levels are too high, nitrification must happen.
