How does nitrogen in dead organisms get released back into soil?
A dead organisms nitrogen rich compounds are taken in by decomposers or are released back into the environment. The compounds are either recycled again by soil micro-organisms or are converted by detrifying bacteria back into nitrogen gas.Answer this question…
Who breaks the dead organisms body back into inorganic nitrogen?
Decomposers such as bacteria and fungi break down dead organisms' bodies into inorganic nitrogen through the process of decomposition. This results in the release of nitrogen back into the soil, where it can be taken up by plants for growth.
What converts nitrogen in the nitrogen cycle?
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
How do living organisms obtain their nitrogen requirement?
All organisms need nitrogen to live and grow. Plants take up nitrate ions from the soil, they are then absorbed into roots by active transport, the plant then produces nitrogen-containing compounds such as protein. This nitrogen then gets into the food web as primary consumers feed on plants and obtain the nitrogen-containing compounds. However, the atmosphere is made up of 78% nitrogen and is unavailable in this form to organisms. This is due to the triple bond between the two N atoms causing it to be inert. To be used by organisms, it must be converted to a chemically available form, such as ammonium (NH4+), nitrate (NO3-), or urea ((NH3)2CO). There are five main processes that convert nitrogen to a more accessible form. They are; nitrogen fixation, nitrogen uptake, decay process, nitrification and denitrification. The first process I will talk about is nitrogen fixation. There, the nitrogen is converted to ammonium; it is the only way organisms can obtain nitrogen directly from the atmosphere. The only organism that can fix nitrogen through metabolic process is bacteria from the genus Rhizobium. The nitrogen fixers are usually found on host plants, but there are also nitrogen fixing bacteria found without host plants. They are known as free-living nitrogen fixers, e.g. in the aquatic environment a very important nitrogen fixer would be cyanobacteria. Nitrogen fixation can also be carried out in high-energy natural events, such as lightning and forest fires. The high-energy breaks the triple bond between the two nitrogen atoms producing a significant amount of single nitrogen atoms available for use. The next process is nitrogen uptake, this is where plants or bacteria itself makes use of the ammonia produced by the nitrogen fixing bacteria. The ammonium is converted from NH4+ to N to make protein or other nitrogen containing compounds. A very important process that returns nitrogen back to the nitrogen cycle for use is the decay process. When organisms, die, nitrogen is converted back into inorganic nitrogen by a process called nitrogen mineralization. Decomposers consume the organic matter and this leads to decomposition. Nitrogen contained within the dead organism in converted to ammonium, it is then available for use to plants, or transformed into NO3- (nitrification). Through the nitrogen cycle, food-making organisms obtain necessary nitrogen through nitrogen fixation and nitrification. Nitrogen compounds are returned to atmosphere and soil through decay and denitrification. In crops, few plants are left to decay back into soil, so the nitrogen cycle doesn't supply enough nitrogen to support plant growth. Therefore natural or artificial fertilizers containing NO3- or NH4+ compounds are added.
How do plants and animals get nitrogen is not from the atmosphere?
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
How does nitrogen in dead organisms get released back into soil?

How is the nitrogen in dead organisms released back into the soil?
When dead organisms decay, decomposer organisms break down their tissues and release nitrogen in the form of ammonium. This ammonium is further converted into nitrates by nitrifying bacteria in the soil. These nitrates can then be taken up by plants as nutrients, completing the nitrogen cycle.
What is the difference between nitrogen fixation and ammonification?
Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia by certain bacteria. Ammonification, on the other hand, is the process by which organic nitrogen from dead organisms or waste is converted into ammonia by decomposers like bacteria and fungi. Nitrogen fixation introduces new nitrogen into the ecosystem, while ammonification recycles existing nitrogen.
How does dead organism return inorganic nitrogen back to earth?
How do dead organism return inorganic back to the earth
What is nitrogen mineralization?
Nitrogen mineralization is the process by which organic nitrogen compounds present in soil are converted into inorganic forms such as ammonium (NH4+) and nitrate (NO3-), making nitrogen available for uptake by plants. This process is carried out by soil microorganisms during decomposition of organic matter.
Who breaks the dead organisms body back into inorganic nitrogen?
Decomposers such as bacteria and fungi break down dead organisms' bodies into inorganic nitrogen through the process of decomposition. This results in the release of nitrogen back into the soil, where it can be taken up by plants for growth.
What is the process called where dead organisms and animal wastes are broken down and converted to other nitrogen-containing compounds such as ammonium?
This process is known as ammonification. It involves the decomposers breaking down organic matter into simpler compounds, releasing ammonium ions as a byproduct.
How is nitrogen converted into a form that can be used by animals?
Nitrogen in it's natural form is triple bonded and can not be used by plants or animals. There is a bacteria that can break these triple bonds and then the plant, which " pays ' for this service with sugar, takes up the nitrogen and uses it. Then animal come along and eat the plants and other animals eat the first animals and that way nitrogen is cycled through the animal kingdom.
Where do bacteria in the soil obtain their nitrogen?
Bacteria in soil obtain their nitrogen primarily from organic matter, such as dead plants and animals. They can also obtain nitrogen through nitrogen fixation, a process where certain bacteria convert atmospheric nitrogen into a form that plants can use.
What part of the nitrogen cycle deals with the conversion of nitrogen and waste products or dead organisms into ammonia?
Ammonification is the part of the nitrogen cycle that involves the conversion of nitrogen in waste products or dead organisms into ammonia by decomposers like bacteria and fungi. This process releases ammonia back into the environment for use by plants in assimilation.
What Ashely Olsen favorite animal?
Probably anything dead that she can throw on her back.
How do humans and animals get nitrogen?
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
