green plants do not have the "power" to break the triple bond of N2 molecule. in better words, they do not have suitable enzymes. on the other hand, some bacteria have, the so colled "nitrogen fixing bacteria", living on legume plant roots.
Green plants are unable to absorb gaseous nitrogen directly because they lack the necessary enzymes to convert atmospheric nitrogen (N2) into a form that can be used by the plant, such as ammonium (NH4+) or nitrate (NO3-). Instead, plants rely on nitrogen-fixing bacteria in the soil to convert N2 into a usable form that can be taken up by the roots.
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.
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 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.
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.
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.
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
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.
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.
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.
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.

No they cannot process N. Some bacteria can process N
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.
Consumers obtain nitrogen through the food they eat, as nitrogen is an essential component of proteins. Inorganic nitrogen can also be found in the air we breathe, but our bodies cannot use this form directly.
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycleThey fix nitrogen into forms usable by plants.
