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
What else can I help you with?
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.
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.
Bacteria return nitrogen to the soil by which process?
Bacteria return nitrogen to the soil through a process called nitrogen fixation, where they convert atmospheric nitrogen into a form that plants can use. This allows plants to obtain the necessary nitrogen for their growth and, in turn, enriches the soil with nutrients.
Is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation.
How does the nitrogen cycle work?
In the nitrogen cycle, nitrogen is converted between different chemical forms by different microorganisms. Nitrogen fixation by bacteria converts nitrogen gas into ammonia, which can be taken up by plants for growth. Nitrifying bacteria then convert ammonia into nitrites and nitrates, which are further processed by denitrifying bacteria back into nitrogen gas, completing the cycle.
What converts gaseous nitrogen into ammonia in the nitrogen cycle?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert gaseous nitrogen into ammonia through a process called nitrogen fixation. This process helps make nitrogen available to plants for growth and is a key step in the nitrogen cycle.
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 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 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.
Why is nitrification important in the nitrogen cycle?
Nitrification is important in the nitrogen cycle because it converts ammonia, a form of nitrogen that is not readily usable by plants, into nitrate, which is a form of nitrogen that plants can easily absorb and use for growth. This process helps to replenish the soil with essential nutrients, supporting plant growth and overall ecosystem health.
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.

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.
Where are nitrate found?
Nitrates are found in man-made fertilizers. They are also found in soil after the nitrogen fixating bacteria converts Nitrite to Nitrate (Nitrogen Cycle) which can be utilized by plants and consumed by the consumers.
How does nitrogen fixation play a crucial role in the nitrogen cycle?
Nitrogen fixation is important in the nitrogen cycle because it converts atmospheric nitrogen gas into a form that plants can use to grow. This process is carried out by certain bacteria and other organisms, making nitrogen available for plants to take up and use for their growth and development. This helps to maintain the balance of nitrogen in the environment and supports the growth of plants, which are essential for the food chain.
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.
