Nitrogen cycle begins like every other cycle in the Biogeochemical cycle.Nitrogen is an unstable gas in it's octet form but the normal Nitrogen is stable so during nitrogenation;which is the formation of free Nitrogen in the atmosphere,nitrogen is being broken down during lightening and thunderstorms so,it becomes free in the atmosphere and can now combine with other compounds.
During rainfall,Nitrogen combines with water to form Nitric acids and with sulphur to form NITROGEN SULPHIDE.These two compounds of Nitrogen are then incorporated into the soil during Nitrogen fixation. The soil alone can not convert this Nitrogen into usable or rather consumable Nitrogen so only root noddles of leguminous plants like Beans can convert this nitrogen into usable one because they have nitrogen fixing bacteria like Rhizobium nigricans . But there are also some free living bacteria in the soil named Azotobacter which help in converting this nitrogen in the soil into usable Nitrogen so that plants can use it for growth.
When these nitrogen compounds have been converted into usable nitrogen,plants now use it to produce food energy which are later on eaten upon by animals for growth.This process is called feeding like we all know.
When these plants and animals die,their dead bodies decay and are embedded into the soil.Micro organisms now eat on these dead bodies.A process called putrefaction.These decomposed matters are later on converted into Ammonia in a process called Amonification by nitrogen fixing bacteria.The same Ammonia is converted into Nitrites and later on into nitrates by Nitrosomonas and Nitrobacters bacteria respectively and some of the nitrates are lost into the underneath soil a process called leaching during erosion by water and the nitrates are also absorbed by plants during food chain a process called Assimilation.The nitrates and nitrites are later sent back into the atmosphere during denitrification which is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.
Without forgetting that during thunder storms,Nitrogen is also sent back into the atmosphere.
What else can I help you with?
Is the nitrogen cycle fast or slow in nature?
The nitrogen cycle in nature is relatively slow.
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
The nitrogen cycle involves the process of nitrogen fixation by certain bacteria converting atmospheric nitrogen into forms usable by plants, which are then consumed by animals. Decomposers break down organic matter into ammonia and return nitrogen to the soil. Denitrification by bacteria converts nitrates back to atmospheric nitrogen to complete the cycle.
Which organisms are most critical in the nitrogen cycle?
Bacteria are most critical in the nitrogen cycle, specifically nitrifying bacteria that convert ammonia to nitrites and then nitrates, and denitrifying bacteria that convert nitrates back to nitrogen gas. These organisms play a crucial role in recycling nitrogen in the environment.
What are some key questions to consider when studying the nitrogen cycle?
When studying the nitrogen cycle, key questions to consider include: How do nitrogen-fixing bacteria convert atmospheric nitrogen into a form that plants can use? What role do plants play in absorbing nitrogen from the soil? How do denitrifying bacteria release nitrogen back into the atmosphere? How does human activity, such as agriculture and industry, impact the nitrogen cycle?
What role does bacteria play in the nitrogen cycle?
Bacteria play a crucial role in the nitrogen cycle by converting nitrogen gas in the atmosphere into forms that plants can use, a process called nitrogen fixation. Other bacteria help break down organic matter and release nitrogen back into the soil, completing the cycle.
What is the nitrogen cycle and can you provide a simple explanation of how it works?
The nitrogen cycle is the process by which nitrogen is converted and circulated in the environment. It involves several steps: nitrogen fixation, nitrification, assimilation, ammonification, and denitrification. In simple terms, nitrogen gas in the atmosphere is converted by bacteria into a form that plants can use. Plants then absorb this nitrogen to grow. When plants and animals die, bacteria break down their organic matter, releasing nitrogen back into the soil. This nitrogen can then be used by plants again, completing the cycle.
Is exhausted in the carbon or nitrogen cycle?
it is in the nitrogen cycle
Is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation.
What are the steps in nitrogen cycle?
nitrogen fixation, denitrification, nitrification, amonification are the for steps of the nitrogen cycle.
What cycle depends on the bacteria in these nodules?
Then cycle that depends on bacteria to convert nitrogen gas into ammonia is the nitrogen cycle. This is the part of the cycle called nitrogen fixation.
Cycle which is dependent on bacteria for nitrogen fixation and denitrifcation?
the nitrogen cycle...
What is a sentence nitrogen cycle?
The nitrogen cycle is essential to the maintenance of life.
Use nitrogen cycle in a sentence?
Bacteria are essential to the nitrogen cycle.
How long does it take a betta to complete its nitrogen cycle?
A Betta does not have a "nitrogen cycle"
Can you hide from the nitrogen cycle?
No, the nitrogen cycle is a part of nature. It is nothing to be afraid of.
What cycles are penguins in?
They are in the life cycle,the carbon cycle and the nitrogen cycle. Taylor,11, from Austin, Texas They are in the life cycle,the carbon cycle and the nitrogen cycle.
What are 4 biogeochemical cycles in nature?
