What molecule in the ground is nitrogen found when there is oxygen around?

When oxygen is present in the ground, nitrogen is typically found as molecular nitrogen (N2). This form of nitrogen is inert and is not readily available for use by most organisms.


What percentage of nitrogen is fixed by nitrogen fixing bacteria?

Around 70-80% of nitrogen in the atmosphere is fixed by nitrogen fixing bacteria through a process called nitrogen fixation. This converted nitrogen is then made available for use by plants and other organisms in the environment.


What is the largest storage pool of nitrogen in the biosphere?

The largest storage pool of nitrogen in the biosphere is in the atmosphere, where approximately 78% of the air is composed of nitrogen gas (N2). Nitrogen gas is not readily available for most organisms to use directly, so it must be converted into other forms like ammonia or nitrate by nitrogen-fixing bacteria before it can be utilized by plants and other organisms in the nitrogen cycle.


Give two examples of how nitrogen cycles from the abiotic portion of the environment into living things and back?

Nitrogen can enter living organisms through nitrogen-fixing bacteria in the soil that convert atmospheric nitrogen into a form that plants can use for growth. This nitrogen is then passed through the food chain as animals consume plants. When living organisms die and decompose, nitrogen is released back into the soil as ammonia by decomposers like bacteria and fungi. This ammonia can then be converted into nitrates by nitrifying bacteria, making it available for uptake by plants to continue the nitrogen cycle.


What organisms are responsible for producing nitrogen compounds?

Nitrogen-fixing bacteria, such as those in the genera Rhizobium and Azotobacter, are primarily responsible for converting atmospheric nitrogen into biologically available forms like ammonia. Some cyanobacteria and certain archaea also play a role in nitrogen fixation.

Although air is full of nitrogen it is not available for organisms to readily use. What is nitrogen changed into before being used by living things?

Nitrogen gas in the atmosphere is transformed by nitrogen-fixing bacteria into ammonia or nitrate, which are forms of nitrogen that can be absorbed and utilized by plants and other living organisms.

AMMONIA, NITRATES AND NITRITES


Describe why nitrogen must cycle through an ecosystem?

Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.


Why must nitrogen cycle through an ecosystem?

Nitrogen is essential for the growth and survival of living organisms, as it is a key component of proteins and DNA. The nitrogen cycle facilitates the conversion of nitrogen between different forms that can be utilized by organisms in the ecosystem. This cycling process ensures that nitrogen is continuously available for plants and other organisms to support their growth and metabolism.


What organisms are responsible for producing nitrogen compounds and what is this process called?

Decomposers are responsible for producing nitrogen compounds, This continual transfer of nitrogen from the non living part of the environment to the living part and back again is called the nitrogen cycle.


Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances b?

Nitrogen is changed into ammonia by nitrogen-fixing bacteria in soil and water. This ammonia can then be further converted into nitrites and nitrates by other species of bacteria in a process called nitrification. These nitrates are then used by plants to make proteins and other essential molecules.


Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?

Nitrogen is changed into ammonia and nitrates through the process of nitrogen fixation before being used by living things. This conversion is typically carried out by specialized bacteria in the soil or water.


Can Nitrogen-fixing bacteria convert atmospheric nitrogen into forms of nitrogen that living things can use?

Yes, nitrogen-fixing bacteria can convert atmospheric nitrogen (N2) into forms of nitrogen (such as ammonia or nitrates) that are accessible to living organisms. By carrying out nitrogen fixation, these bacteria play a crucial role in making nitrogen available for plants and other organisms to use for essential biological processes.


What is the difference between free nitrogen and fixed nitrogen?

Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.


Why are producers important to the nitrogen cycle?

Producers, like plants, are important to the nitrogen cycle because they are able to convert atmospheric nitrogen into a form that can be used by living organisms. Through nitrogen fixation, producers play a key role in making nitrogen available for other organisms in the ecosystem.
