How does nitrogen in the air and the soil converted into nitrates?
Nitrogen gas in the air is converted into nitrates through a process called nitrogen fixation by specialized bacteria. In the soil, nitrates are produced through nitrification, a two-step process involving the conversion of ammonium to nitrites and then to nitrates by bacteria.
What changes nitrogen gas into nitrates?
Nitrogen gas is converted into nitrates through a process called nitrogen fixation, which is carried out by certain bacteria in the soil or by lightning strikes. These bacteria take atmospheric nitrogen and convert it into a form that plants can use to grow, known as nitrates.
How is nitrogen in the air converted into nitrates?
Nitrogen in the air is converted into nitrates through a process called nitrogen fixation, where certain types of bacteria or lightning convert atmospheric nitrogen gas (N2) into ammonia (NH3) or nitrate (NO3-). These nitrates can then be taken up by plants and incorporated into their tissues.
Outline the major steps in the nitrogen cycle?
Nitrogen fixation: Bacteria convert atmospheric nitrogen into ammonia. Nitrification: Ammonia is converted into nitrites and then nitrates by nitrifying bacteria. Assimilation: Plants and other organisms take up nitrates to build proteins and nucleic acids. Ammonification: Decomposers break down organic matter releasing ammonia back into the soil. Denitrification: Denitrifying bacteria convert nitrates back into atmospheric nitrogen, completing the cycle.
How do nitrates get into urine?
Nitrates can enter urine through dietary ingestion of nitrates from foods such as leafy green vegetables, root vegetables, and processed meats. The body metabolizes dietary nitrates into nitrites, which are then excreted in the urine.
What are the major parts in the nitrogen cycle?
The major parts of the nitrogen cycle include nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium into nitrites and nitrates by bacteria), denitrification (conversion of nitrates back into atmospheric nitrogen), and assimilation (incorporation of nitrogen into plant and animal tissues).
What are two ways by which nitrogen can combine and form nitrates?
Nitrogen can combine and form nitrates primarily through two processes: biological nitrification and atmospheric nitrogen fixation. In biological nitrification, soil bacteria convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-) through a series of oxidation reactions. In atmospheric nitrogen fixation, lightning or certain bacteria convert atmospheric nitrogen (N2) into ammonia, which can subsequently be oxidized into nitrates by soil microorganisms.
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.

Are bacteria that live in the root systems of legumes?
these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
The conversion of nitrates to nitrogen gas by bacteria is called?
Nitrogen Fixation.
3 Describe two ways in which nitrates can be replaced naturally in the soil?
1. lightning makes nitrates from nitrogen and oxygen in the air. the nitrates then get washed into the soil by rain. 2. animal and plants decompose- depositing organic nitrogen into the soil
Nitrates are turned back into nitrogen gas by?
denitrifying bacteria in the soil through a process called denitrification. This conversion helps regulate nitrogen levels in the environment and reduce the potential for water pollution from nitrates.
What organisms are responsible for keeping the nitrogen cycle flowing?
Various bacteria are responsible for carrying out key processes in the nitrogen cycle. For example, nitrogen-fixing bacteria convert atmospheric nitrogen into a form usable by plants. Other bacteria, like nitrifying bacteria, convert ammonium into nitrates, which can then be used by plants. Denitrifying bacteria convert nitrates back into atmospheric nitrogen, closing the cycle.
Atmospheric nitrogen is fixed by?
Atmospheric nitrogen is fixed by certain bacteria, such as Rhizobium and Azotobacter, through a process called nitrogen fixation. These bacteria convert atmospheric nitrogen into a form that plants can use, such as ammonia or nitrates, helping to enrich the soil with essential nutrients for plant growth.
How is nitrogen in the air converted into nitrates?
Nitrogen in the air is converted into nitrates through a process called nitrogen fixation, where certain types of bacteria or lightning convert atmospheric nitrogen gas (N2) into ammonia (NH3) or nitrate (NO3-). These nitrates can then be taken up by plants and incorporated into their tissues.
