The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen".
Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.

What are the two ways nitrogen can be fixed?
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
What is nitrogen changed into before being used by living things?
Nitrogen is changed into ammonia through a process called nitrogen fixation, typically carried out by soil bacteria or certain plants like legumes. Ammonia is then converted into other forms of nitrogen such as nitrites and nitrates that are taken up by plants for growth and utilized by other living organisms in the food chain.
Two ways by which plants get nitrogen compounds?
Plants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.
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

What are two major ways in which nitrogen is fixed in ecosystems?
Nitrogen can be fixed in ecosystems through biological processes, like by nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for plants. It can also be fixed through human activities, such as the use of nitrogen fertilizers in agriculture.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
How do thunderstorms help in converting nitrogen to nitrates?
The short answer is yes. I am not sure about the amount but there are only two ways nature converts N2 into a form of nitrogen that is usable by plants. The two ways are microorganisms and lightning. I believe bacteria are the main nitrogen fixers, but there might also be some algae that convert nitrogen as well. We have also mastered fixing N2, the process is the Haber- Bosh process.
What are two ways nitrogen becomes usable two plants humans and animals?
Amino acids, proteins and DNA.

What is meant by nitrogen fixation state two ways in which nitrogen gas of the atmosphere can be fixed in nature to get nitrogen compound in the soil?
Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.
Two ways by which plants get nitrogen compounds?
Plants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.
What are two functions of plants and animals in the nitrogen?
plants and animals
What are two ways nitrogen becomes unusable?
Nitrogen can become unavailable to plants if it is locked up in organic matter and unavailable for uptake. It can also be lost to the atmosphere through denitrification, where certain bacteria convert nitrogen compounds back into nitrogen gas.
Which bacteria live in soil and fix nitrogen as part of the nitrogen cycle?
Leguminous plants contain symbiotic bacteria called Rhizobia within nodules root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilise the soil.
What are the two ways that atmospheric nitrogen gets into the ground?
Atmospheric nitrogen can enter the ground through nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that plants can use. It can also be deposited into the ground through rainfall as nitric acid or ammonium ions.
