ammonification
It is usually performed by soil-living bacteria, such as nitrobacter.
The smell that occurs after rain on dry soil or sand is called petrichor. It is caused by a combination of bacteria, specifically actinomycetes, and other compounds such as geosmin released from the soil when it is moistened by rain.
The two main groups of bacteria responsible for nitrogen fixation are Rhizobium found in legume root nodules, and Azotobacter found in the rhizosphere of various plants. Rhizobium forms a mutualistic relationship with legumes, providing fixed nitrogen in exchange for sugars, while Azotobacter functions as a free-living nitrogen fixer in the soil.
Bacteria is responsible for recycling of materials.
decomposers
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
none
It is usually performed by soil-living bacteria, such as nitrobacter.
The process responsible for returning nitrogen to the air is denitrification, carried out by denitrifying bacteria in the soil. During denitrification, these bacteria convert nitrates in the soil back into nitrogen gas, which is released into the atmosphere.

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.
they decomposed the materials in the soil
change the soil
sometimes herbivores are responsible for the removal of soil .how?
The bacteria responsible for causing a fishy odor is called trimethylamine-producing bacteria.
Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.
There can be billions to trillions of bacteria in 1 gram of sandy soil, depending on various factors such as soil composition, moisture content, and nutrient availability. Bacteria play a crucial role in soil health and ecosystem functioning.
