What process has changed the percentage of nitrogen in the earth's atmosphere?
The process that has changed the percentage of nitrogen in the Earth's atmosphere is biological nitrogen fixation, where certain bacteria convert nitrogen gas into a form that plants can use. This has led to an increase in nitrogen levels over time.
Which process describes nitrogen fixation?
Bacteria combines with hydrogen to make ammonia, which is changed and turned into compounds such as nitrate or nitrogeNitrogen fixation is the natural process, either biological or abiotic, by which nitrogen (N2) in the atmosphere is converted into ammonia (NH3).
How does atmospheric nitrogen enter the soil?
Atmospheric nitrogen can enter the soil through a process called nitrogen fixation, where certain bacteria convert nitrogen gas from the air into a form that plants can use. This can occur naturally through biological processes or through human activities such as the use of nitrogen-based fertilizers.
What is one way that atmospheric nitrogen enters the soil directly?
Atmospheric nitrogen can enter the soil directly through a process called nitrogen fixation, where specialized bacteria convert atmospheric nitrogen gas into forms that plants can use, such as ammonium or nitrate.
How does nitrogen fixation work in the process of converting atmospheric nitrogen into a form that plants can use for growth?
Nitrogen fixation is the process of converting atmospheric nitrogen into a form that plants can use for growth. This is done by certain bacteria, like Rhizobium, that live in the roots of leguminous plants. These bacteria have the enzyme nitrogenase, which converts atmospheric nitrogen into ammonia, a form of nitrogen that plants can absorb and use for their growth.
What is the term for the biological process where by atmospheric nitrogen is changed into a form usable by plant?
Nitrogen fixation.
What is the term for the biological process whereby atmospheric nitrogen is changed into a form usable by plants?
Nitrogen fixation.

The term nitrogen fixation refers to the?
biological process where certain microorganisms convert atmospheric nitrogen into forms that plants can use for growth, such as ammonia or nitrate. This process is essential for maintaining soil fertility and the overall nitrogen cycle in ecosystems.
What are three ways for nitrogen to be fixed?
Biological nitrogen fixation: Certain bacteria, like rhizobia, can convert inert atmospheric nitrogen into ammonium. Industrial nitrogen fixation: The Haber-Bosch process takes atmospheric nitrogen and hydrogen to produce ammonia for fertilizers. Lightning: Nitrogen fixation can also occur through lightning strikes, which provide the energy needed to convert nitrogen gas into reactive nitrogen compounds.
Which nutrient is changed by bacteria into different forms?
Nitrogen is a nutrient that is changed by bacteria into different forms through a process called nitrogen fixation. Bacteria can convert atmospheric nitrogen (N2) into forms that plants can use, such as ammonium (NH4+) or nitrate (NO3-). This process is important for bringing nitrogen into the ecosystem and making it available for plant growth.
What does it mean to have nitrogen fixed?
Nitrogen fixation is the conversion of atmospheric nitrogen, N2, into some biological form, such as ammonia, NH3, or nitrogen dioxide, NO2. In nature, this process is most often completed by nitrogen-fixing bacteria or diazotrophs. Nitrogen fixation is important because only fixed nitrogen can be used for basic biological substances such as proteins and nucleic acids.
What is the process of combining free nitrogen with other elements?
The process of combining free nitrogen with other elements is called nitrogen fixation. This can occur through biological processes such as symbiotic relationships with certain plants and bacteria, or through non-biological processes such as lightning and industrial methods like the Haber-Bosch process. In these processes, atmospheric nitrogen is converted into forms that can be utilized by living organisms, such as ammonia or nitrate.
What is nitroginase?
Nitrogenase is an enzyme responsible for the biological conversion of atmospheric nitrogen gas into ammonia, which can be used by plants to synthesize essential biomolecules like proteins and nucleic acids. This process is called nitrogen fixation and is crucial for the nitrogen cycle in ecosystems.
What chemical cycle uses bacteria to fix gases from the air?
The nitrogen cycle uses bacteria to fix atmospheric nitrogen gas into a form that plants can use, a process known as nitrogen fixation. This bacteria, such as Rhizobium and Azotobacter, convert nitrogen gas into ammonia through biological processes.
