What are the four stages of the nitrogen cycle?
The four stages of the nitrogen cycle are nitrogen fixation, nitrification, assimilation, and denitrification. During nitrogen fixation, nitrogen gas is converted into ammonia by bacteria. Nitrification involves the conversion of ammonia into nitrites and nitrates. Assimilation is the process of incorporating nitrogen into living organisms. Denitrification converts nitrates back into nitrogen gas.
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 converts ammonia to urea?
The urea cycle, which occurs in the liver, converts ammonia to urea. The urea cycle involves a series of reactions that ultimately result in the production of urea, which is then excreted by the kidneys in urine. This process helps to safely remove excess ammonia from the body.
What bacteria converts nitrogen into compounds?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert atmospheric nitrogen into compounds like ammonia that can be used by plants. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available in a form that other organisms can use for growth.
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 is the bacteria that turns nitrogen to ammonia?
The bacteria that converts nitrogen gas into ammonia is known as nitrogen-fixing bacteria. Some examples of nitrogen-fixing bacteria include Rhizobium, Azotobacter, and Clostridium. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available to plants.

7. Which cycle does not have a gaseous phase?
nitrogen cycle
Which organisims help convert gaseous nitrogen into ammonia in the nitrogen cycle?
In the nitrogen cycle, nitrogen-fixing bacteria play a crucial role in converting gaseous nitrogen (N₂) into ammonia (NH₃). These bacteria, such as Rhizobium, live in the root nodules of legumes or in the soil, where they convert atmospheric nitrogen into a form that plants can use. Additionally, some free-living bacteria, like Azotobacter, also perform this nitrogen fixation in the soil. This process is essential for replenishing the nitrogen available to plants and, consequently, the entire ecosystem.
What is the bacteria in the soil can break down the ammonia into gaseous form of nitrogen?
The bacteria in the soil that can break down ammonia into gaseous nitrogen are primarily known as denitrifying bacteria. These bacteria, such as those from the genera Pseudomonas and Bacillus, convert ammonia (NH3) and nitrites (NO2-) into nitrogen gas (N2) or nitrous oxide (N2O) through a process called denitrification. This process is an essential part of the nitrogen cycle, helping to reduce excess nitrogen in the soil and return it to the atmosphere.
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.
What is the role of nitrosomonas and nitrabactor in nature?
Nitrosomonas converts ammonia into nitrite in the nitrification process, while Nitrobacter converts nitrite into nitrate. Both are essential in the nitrogen cycle, converting various forms of nitrogen to make it available to plants for growth.
In the nitrogen cycle what are 3 different chemical transformation?
In the nitrogen cycle, three key chemical transformations include nitrogen fixation, nitrification, and denitrification. Nitrogen fixation converts atmospheric nitrogen (N₂) into ammonia (NH₃) through the action of certain bacteria or lightning. Nitrification then transforms ammonia into nitrites (NO₂⁻) and subsequently into nitrates (NO₃⁻) via specialized bacteria. Finally, denitrification reduces nitrates back into nitrogen gas (N₂), returning it to the atmosphere and completing the cycle.
Is ammonia part of the nitrogen cycle?
yes
What molecules are involved in the nitrogen cycle?
The nitrogen cycle involves several key molecules, including nitrogen gas (N₂), ammonia (NH₃), nitrites (NO₂⁻), nitrates (NO₃⁻), and organic nitrogen compounds. Nitrogen fixation converts atmospheric N₂ into ammonia, which can be further oxidized to nitrites and then nitrates through nitrification. Denitrification processes reduce nitrates back to nitrogen gas, completing the cycle. Additionally, organic matter decomposition releases organic nitrogen back into the soil, making it available for uptake by plants.
What converts ammonia to urea?
The urea cycle, which occurs in the liver, converts ammonia to urea. The urea cycle involves a series of reactions that ultimately result in the production of urea, which is then excreted by the kidneys in urine. This process helps to safely remove excess ammonia from the body.
