Nitrogen cycle in order?
The nitrogen cycle begins with nitrogen fixation, where nitrogen gas is converted into ammonia by bacteria. Ammonia is then converted into nitrites and nitrates by nitrifying bacteria. Plants take up nitrates as nutrients, which are then consumed by animals. Finally, denitrifying bacteria break down nitrates back into nitrogen gas, completing the cycle.
What bacteria convert nitrites into nitrates?
Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
Put the steps of the nitrogen cycle in order starting with the step that removes nitrogen from the atmosphere?
N2 molecules break apart via nitrogen-fixing bacteria. Other living entities such as plants and animals ingest nitrogen in nitrate-containing compounds. Organic matter decays via decomposers. N2 is formed via denitrifying bacteria.
How are the process of nitrogen fixation and denitrification different?
nitrification= it is the conversion of ammonia first into nitrites then into nitrates by nitrifying bacteria. dentrification=it is the conversion of nitrites and nitrates into free nitrogen.
Why are bacteria important to the nitrogen cycle?
because when bacteria convert ammonia into nitrates and nitrites, producers need them to make proteins, and then consumers eat the producers and reuse the nitrogen to make their own proteins.
In the nitrogen cyclebacteria fix nitrogen from the atmosphere to form?
In the nitrogen cycle, bacteria fix nitrogen from the atmosphere to form ammonia. This ammonia can then be converted into nitrites and nitrates by other bacteria in the soil, which plants can absorb to use for growth. Nitrogen eventually returns to the atmosphere through denitrification by bacteria.
The process by which nitrites and nitrates are produced by bacteria in the soil?
Nitrites and nitrates are produced by nitrifying bacteria in the soil through a process known as nitrification. Ammonia or ammonium ions are first converted to nitrites by Nitrosomonas bacteria, and then further converted to nitrates by Nitrobacter bacteria. These nitrates can then be taken up by plants as a source of nitrogen for growth.
Which parts of the nitrogen cycle are involved in moving nitrogen from the atmosphere into the soil?
The processes involved are nitrogen fixation, where nitrogen gas is converted into ammonia by nitrogen-fixing bacteria, and nitrification, where ammonia is converted into nitrites by nitrifying bacteria, and then further into nitrates. These nitrates are then readily available for uptake by plants for growth and development.
What organism turns nitrates back into nitrogen gas?
Denitrifying bacteria are responsible for converting nitrates back into nitrogen gas as part of the nitrogen cycle. These bacteria thrive in oxygen-poor environments and break down nitrates into nitrites and eventually into nitrogen gas.
What is bacteria turning usable nitrogen into nitrogen gas?
The process of bacteria turning usable nitrogen into nitrogen gas is called denitrification. This occurs when certain bacteria convert nitrates or nitrites back into nitrogen gas, which is released into the atmosphere. This can result in a loss of available nitrogen for plants and other organisms.
What organisms are necessary for producing ammonia nitrates and nitrites during the nitrogen cycle?
Bacteria, specifically nitrifying bacteria, play a crucial role in the nitrogen cycle by converting ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-). These bacteria include Nitrosomonas and Nitrobacter, which are responsible for these conversions.
Which type of bacteria return nitrogen to air?
nitrites
What is the process that converts ammonia into nitrates?
The process that converts ammonia into nitrates is called nitrification. It involves two steps: first, ammonia is oxidized by bacteria into nitrites, and then the nitrites are further oxidized into nitrates by another group of bacteria. This process is important in the nitrogen cycle as it makes nitrogen available to plants for growth.
What are three products of nitrogen fixation?
Ammonia, nitrates, nitrites
Are bacteria that live in the root systems of legumes?
these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
Nitrogen cycle in order?

What Converts dead matter to soil nitrates or nitrites?
The process of decomposition by decomposers such as bacteria and fungi converts dead matter into soil nitrates or nitrites. These organisms break down organic material, releasing nitrogen in the form of nitrates or nitrites as a byproduct, which can then be used by plants for growth.
