Chemoautotrophs like Nitrogen fixing bacteria
I think that it is earthworms that do that.
These are the diazotrophs bacteria.
Nitrogen fixing bacteria.
Nitrogen
This is called the nitrogen cycle.Nitrogen is an inert gas and does not form compounds very easily, but it is a vital component in proteins needed for life on Earth. It is made to form compounds in two ways :-Using the energy on the inside of lightning strikesUsing specialist bacteria called nitrogen fixing bacteria that are to be found in association with the roots of (particularly) leguminous plants.Once in a compound form life can absorb and use it to make proteins and it becomes part of the biosphere passing from one organism to the next as part of the food chain. In certain instances vast of nitrogen rich deposits can form as birds or bats make mound of their droppings (guano). Eventually however the organic compounds containing the nitrogen are broken down by decomposer organisms and the nitrogen get released again as an atmospheric gas.In recent time humans have learned how to make nitrogen fertilizers, taking nitrogen out of the air and making compounds out of it using the energy of fossil fuels to do this. This unnatural excess of nitrogen added into the nitrogen cycle can and does upset the environment and is responsible for algal blooms in lakes etc.
Respiration in an organism is linked to the carbon cycle but not the nitrogen cycle.

Nitrogen fixation is carried out by nitrogen fixing bacteria in the nodules of the roots of legumes, and in the soil.
When nitrogen is inhaled at high pressure (over 4 atmospheres) in organism is the cause of nitrogen narcosis.
Bacteria is the the most responsible organism that converts nitrogen into nitrates. Which plants can then use.

All organisms are composed of the chemicals of life. This includes carbon, hydrogen, nitrogen, oxygen and the many compounds made from these elements.

Nitrogen cycle
Bacteria is the organism most critical in the nitrogen cycle. Bacteria in the nitrogen cycle provides different forms of nitrogen compounds used by higher organisms.
There are nitrogen compounds, water, carbon dioxide, phosphates, sulfates, indoles, medicals, food additives and other things that cannot be used by the organism.
Respiration in an organism is linked to the carbon cycle but not the nitrogen cycle.
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.
Some do and some do not. Water-soluble compounds can pass out of an organism fairl easily. Some compounds, such as DDT, however, do not leave the body.
