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.
Can nitrogen be directly used by living things?
No, nitrogen gas cannot be directly used by most living organisms. Instead, nitrogen-fixing bacteria in the soil or in plant roots convert atmospheric nitrogen into a form (ammonia or nitrates) that can be used by plants to make proteins. Other organisms then obtain nitrogen by consuming these plants.
During nitrogen fixation nitrogen gas is converted into a form that what can use?
During nitrogen fixation, nitrogen gas is converted into ammonia or other forms of usable nitrogen by nitrogen-fixing bacteria. This process is important because plants and other organisms cannot use atmospheric nitrogen directly in this form.
What is the role that nitrogen plays as essential to the production of proteins?
Nitrogen is a key component of amino acids, the building blocks of proteins. Plants absorb nitrogen from the soil to synthesize amino acids, which are then used to produce proteins needed for growth and development. Without nitrogen, plants cannot create proteins, which are essential for various cellular functions.
What are forms of nitrogen that are unable by humans?
Nitrogen gas (N2) in our atmosphere is an example of a form of nitrogen that humans cannot directly use. Additionally, nitrate (NO3-) in soils is not directly usable by humans and must first be converted by plants into a more bioavailable form of nitrogen.
Is it true most nitrogen fixation is performed by plants?
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
Can nitrogen gas be used by plants?
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
Is it true although 78 percent of air is nitrogen plants cannot use this form well?
Yes, plants require nitrogen in a form that is biologically available, such as ammonia or nitrate, as they cannot directly utilize atmospheric nitrogen. Certain nitrogen-fixing bacteria assist in converting atmospheric nitrogen into a usable form for plants through a process called nitrogen fixation.
Why is nitrogen gas in the atmosphere useless to plants?
Plants cannot use nitrogen gas directly because they lack the necessary enzymes to convert atmospheric nitrogen gas (N2) into a usable form like ammonia (NH3) or nitrate (NO3-). Instead, plants rely on specialized bacteria in the soil called nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that plants can use for growth.
what form is nitrogen that cannot be used by plants?
Nitrogen in its atmospheric form, which is N₂ (nitrogen gas), cannot be used directly by plants. This gaseous nitrogen makes up about 78% of the Earth's atmosphere, but plants require nitrogen in a fixed form, such as ammonium (NH₄⁺) or nitrate (NO₃⁻), for uptake and utilization. Nitrogen fixation processes, such as those carried out by certain bacteria, convert atmospheric nitrogen into these usable forms.
Why are nitrogen-fixing bacteria contributions to the nitrogen cycle important?
The air is about 80% nitrogen- but cannot be used by plants for food. Nitrogen fixing bacteria transform nitrogen in the air to nitrogen in the soil that plants CAN use- resulting in greatly improved plant growth, and more fertile soil.

Can plants proces nitrogen?
No they cannot process N. Some bacteria can process N
Why do plants consume nitrogen?
Nitrogen is considered to be a limiting factor for plants since it cannot be absorbed as a gas. Plants will use ammonia as their main source fro nitrogen.
What happens during nitrogen fixation and how does it contribute to the process of converting atmospheric nitrogen into a form that plants can use for growth?
During nitrogen fixation, certain bacteria convert atmospheric nitrogen gas into a form that plants can use, such as ammonia or nitrate. This process is essential for plants to obtain the nitrogen they need for growth, as they cannot use atmospheric nitrogen directly. The bacteria involved in nitrogen fixation play a crucial role in making nitrogen available to plants, ultimately supporting their growth and development.
