Nitrogen is the critical component of amino acids, which are the building blocks of protein. Since all organisms need protein for their cellular structure, no organism, that we know of, can exist without some nitrogen. There are different modes of acquiring nitrogen, however. The legumes, such as beans, are plants that can "fix" atmospheric nitrogen into amino acids, and thus do not need to acquire it from other organisms, like we do. There are also some bacteria that are capable of fixing nitrogen.
When an organism dies the nitrogen in its body it is released by action of decomposers. A desert is a biome that is very dry and little precipitation.
Well, most of the Nitrogen in an organism's body is excreted as urine, urea or ammonia.

Chemoautotrophs like Nitrogen fixing bacteria
Nitrogen fixation is carried out by nitrogen fixing bacteria in the nodules of the roots of legumes, and in the soil.
Conversion of inert elemental nitrogen gas into biologically usable form is called nitrogen fixation. Organism that performs nitrogen fixation is Rhizobium Leguminous.
Photosynthesis is a process in an organism that is linked to the carbon cycle but not the nitrogen cycle. In photosynthesis, carbon dioxide is taken up by plants to produce glucose and oxygen, which are important components of the carbon cycle. However, nitrogen is not directly involved in this process.
Conversion of inert elemental nitrogen gas into biologically usable form is called nitrogen fixation. Organism that performs nitrogen fixation is Rhizobium Leguminous.
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are responsible for converting atmospheric nitrogen into nitrates through a process called nitrogen fixation. These bacteria can be found in the soil and form symbiotic relationships with plants to provide them with usable forms of nitrogen.
