Nitrogen must be in the form of ammonia (NH3), nitrate (NO3−), or nitrite (NO2−) to be used by living organisms. These forms are essential for synthesizing amino acids and nucleotides, which are critical for proteins and genetic material. Plants typically absorb nitrate and ammonium from the soil, while animals acquire nitrogen by consuming plants or other animals.
What else can I help you with?
What is the ultimate source of the nitrogen that living things use?
The ultimate source of nitrogen that living things use is the atmosphere, which is composed of about 78% nitrogen gas (N₂). This atmospheric nitrogen is not directly usable by most organisms, so it must be converted into a biologically available form through processes like nitrogen fixation, carried out by certain bacteria and archaea. These microorganisms convert atmospheric nitrogen into ammonia or related compounds, which can then be utilized by plants and, subsequently, by animals that consume those plants.
Why is nitrogen fixation important to living things?
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
Can all living thins absorb nitrogen directly from the atmosphere?
No, not all living things can absorb nitrogen directly from the atmosphere. Most organisms, including plants and animals, rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into forms they can use, such as ammonia or nitrates. Certain plants, particularly legumes, have symbiotic relationships with these bacteria that enable them to access nitrogen. However, the majority of life forms must obtain nitrogen through the food chain or soil.
Is nitrogen a natural resource?
Yes, nitrogen is a natural resource found in the Earth's atmosphere. It is an essential element for all living organisms and plays a crucial role in various biological processes, such as plant growth and nutrient cycling.
What form must nitrogen take before plants and animals can use it?
Nitrogen must be in the form of ammonium (NH4+) or nitrate (NO3-) before plants and animals can use it for growth and development. These forms of nitrogen can be taken up by plant roots and further utilized in biological processes.
Why must living organisms rely on nitrogen fixation for their source of nitrogen?
Biology relies on chemistry. The nitrogen must be able to attach to the receptor molecule to be used. Nitrogen fixation renders nitrogen into a less s table form so that it can break bonds and attach to other molecules.
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 is the ultimate source of the nitrogen that living things use?
The ultimate source of nitrogen that living things use is the atmosphere, which is composed of about 78% nitrogen gas (N₂). This atmospheric nitrogen is not directly usable by most organisms, so it must be converted into a biologically available form through processes like nitrogen fixation, carried out by certain bacteria and archaea. These microorganisms convert atmospheric nitrogen into ammonia or related compounds, which can then be utilized by plants and, subsequently, by animals that consume those plants.
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.

What form must the nitrogen be in?
In order to be used by most plants, nitrogen must be in the form of nitrate (NO3-) or ammonium (NH4+). Plants cannot directly use atmospheric nitrogen (N2) as a nutrient source.
Why must matter such as water carbon oxygen and nitrogen be recycled in the environment?
Matter such as water, carbon, oxygen, and nitrogen must be recycled in the environment because they are essential for sustaining life. These elements are continuously used by living organisms in various processes such as respiration, photosynthesis, and nutrient cycling. Recycling ensures that these elements are continually available for different organisms to utilize, promoting ecosystem balance and health.
What must happen to nitrogen before plants and animal can use it?
Nitrogen must be in the compound form before it is used by plants or animals
Why do animals not obtain nitrogen from the air?
Nitrogen gas is fairly inert and so is difficult for organisms to process. Instead, animals must get usable nitrogen compounds from their food.
What is it called when living things must get their energy by consuming others?
It is called heterotrophy, where living organisms rely on consuming other organisms for energy in the form of organic compounds.
What does nitrogen do for organisms?
nitrogen is not only the building blocks of protein, of which muscles and many other of the body's parts are made, but also the basic constituent of DNA, which carries the genetic code for all living things. Nitrogen atoms must also be present in molecules of ADP and ATP, which enable energy transfer during photosynthesis.
