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.
Bacteria in soil change this to a form that can used by plants is what?
Nitrogen gas (N2) is converted by nitrogen-fixing bacteria that live in the root nodules of Legumes into NH3.
Where do bacteria fix nitrogen gas?
Some bacteria fix nitrogen gas in the soil, forming a symbiotic relationship with plants by converting atmospheric nitrogen into a form that plants can use for growth. Other bacteria, like cyanobacteria, fix nitrogen gas in aquatic environments like oceans and freshwater bodies, contributing to the overall nitrogen cycle.
How is nitrogen gas processed or changes so that plant cells can use it?
Nitrogen gas is converted into a form that plant cells can use through a process called nitrogen fixation. This can be done by certain bacteria that live in the soil or in the root nodules of leguminous plants. These bacteria convert nitrogen gas into ammonia, which can then be taken up by plant roots and used to synthesize proteins and other essential molecules.
What do nitrogen fixing bacteria use to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen?
Nitrogen fixing bacteria use an enzyme called nitrogenase to split molecules of nitrogen gas (N2) and combine the nitrogen atoms with hydrogen to form ammonia (NH3) through a process called nitrogen fixation. This ammonia is then used by plants as a source of nitrogen to synthesize amino acids and proteins.
What atmospheric gas can only be used by plants when transformed by bacteria first?
Nitrogen
What natural processes renew supply of nitrogen in the atmosphere?
Nitrogen-fixing bacteria in the soil and roots of certain plants convert nitrogen gas from the atmosphere into a form that plants can use. Lightning also plays a role in converting nitrogen gas into compounds that can be used by plants.

Which gas is changed into a useful form for the plants by the bacteria in the soil?
Nitrogen gas is changed into a useful form for plants by nitrogen-fixing bacteria in the soil. These bacteria convert nitrogen gas into a form that plants can absorb and use to grow, known as ammonium or nitrate.
Which organisms convert nitrogen gas into a form that is usable by plants?
Nitrogen-fixing bacteria, like Rhizobium and Azotobacter, convert nitrogen gas into ammonia, which can be taken up by plants and used to support their growth. Some cyanobacteria and certain types of archaea are also capable of fixing nitrogen.
Describe the path of nitrogen through its biogeochemical cycle?
Nitrogen gas in the soil is used by plants, which are eaten by animals. The waste products of the animals contain the nitrogen. It is broken down by bacteria, which releases nitrogen gas into the atmosphere, and the cycle repeats.
Which gas makes up 78 percent of our atmosphere but can be used by plants only when transformed by bacteria first?
Nitrogen gas makes up 78% of our atmosphere, but plants can only use it when it is transformed into a usable form by nitrogen-fixing bacteria, such as Rhizobium or Azotobacter. This conversion process allows plants to absorb the nitrogen in the form of ammonia or nitrates.
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.
What is the characteristics and properties of nitrogen gas?
the nitrogen gas is used for nitrogen fixation
Which gas makes up 78 percent of our atmosphere but can be used by plants only when transformed by bacteria?
nitrogen-
Nitrogen-fixing bacteria in soil turns nitrogen gas into water?
This is incorrect. Nitrogen-fixing bacteria in soil convert atmospheric nitrogen gas (N2) into a form of nitrogen (NH3 or NH4+) that plants can use for growth, not water. Water is a separate entity in the nitrogen cycle and does not participate in nitrogen fixation by these bacteria.
What gas makes up 78 percent of your atmosphere but can be used by plants only when transformed by bacteria first?
Nitrogen. The bacterial transformation is needed to break the triple bonds of diatomic atmospheric nitrogen, something plants can't do, so these bacteria fix the nitrogen into a usable form in exchange for plant sugar
