What organism is responsible for converting nitrogen into nitrates?
Bacteria is the the most responsible organism that converts nitrogen into nitrates. Which plants can then use.
What organisms convert nitrogen into a form that is usable by humans?
Bacteria Ammonia, nitrates, nitrites
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.
How does different types of bacteria act to increase nitrate concentration in the soil?
nitrifying bacteria turns ammonia in decaying matter into nitrates as well as decomposer bacteria decomposed proteins and urea and turns them into ammonia
What process do certain prokaryotes use nitrates or sulfates rather than oxygen as the terminal electron acceptor?
"Anaerobic respiration" doesn't require oxygen. True anaerobic respiration involves an electron acceptor other than oxygen. Bacteria are capable of using a wide variety of compounds as terminal electron acceptors in respiration: nitrogenous compounds (such as nitrates and nitrites), sulfur compounds (such as sulfates, sulfites, sulfur dioxide, and elemental sulfur), carbon dioxide, iron compounds, manganese compounds, cobalt compounds, and uranium compounds.

How does bacteria help make fertile more soil?
Rhizobium bacteria absorb nitrogen gas from atmosphere and convert it into nitrogenous compounds called nitrates. the roots decompose the nitrates present in the root nodules mix with the soil enrich it with the nitrogenous compounds and hence increase the soil fertility.
What is the function of nitrifying bacteria?
Nitrifying bacteria converts ammonia compounds into nitrites and nitrates while denitrifying converts the nitrates into atmospheric nitrogen gas. It is confusing as at first I thought that the denitrifying bacteria would convert the nitrates into ammonia, but that is wrong. Denitrification is the opposite to nitrogen fixation, not nitrification.
What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
Does Organic compound contain carbon and are usually found in living matter?
Yes,Organic compound are usually found in living matter but they do not contain carbon .They contain nitrogenous compounds which convert into nitrates by nitrifying bacteria.
Why nitrogenous compounds are used in fertilizer?
Basically nitrogen is nitrate and nitrates are a Mineral used in plant growth
What are salts that are converted to nitrites by bacteria?
Nitrates
Bacteria changes nitrates in what way?
Bacteria breath in nitrogen and breath out nitrate/
By what process do nitrates enter the cell?
Nitrates enter the cell through the process of active transport. Nitrates are essential for development of leaves of a plant and are absorbed through root hair cells.
What do plants use nitrites and nitrates to form?
Sometimes proteins and sometimes the nitrogenous bases in their genetic material (DNA/RNA)
Why is the disposal of nitrogenous waste a problem for animals but not for plants?
The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.
What dangers do high level nitrates in the drinking water present for infants?
Humans and other animals usually have bacteria that convert nitrates into nitrates in their large intestines. For adults, the presence of these bacteria in the digestive system is not harmful, because the stomach of an adult is so acidic that the bacteria cannot survive. But the stomach of an infant is much less acidic, so the bacteria can move up into the stomach, where they will convert nitrates into nitrites. The nitrites can then pass into the blood of the infant.
