Nitrogen is available to plants only in the form of?
Nitrogen is available to plants in the form of nitrates (NO3-) or ammonium (NH4+). Plants typically take up these forms of nitrogen through their roots for growth and development.
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.
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.
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

Why can't animals use nitrogen in the air?
Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil cuz bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria a.k.a. blue-green algae transform the nitrogen from the atmosphere into usable forms of nitrate
How do legumes contribute to the nitrogen content in soil?
Legumes have a special ability to form a symbiotic relationship with certain bacteria in their roots. These bacteria, called rhizobia, can take nitrogen from the air and convert it into a form that plants can use. This process, known as nitrogen fixation, allows legumes to increase the nitrogen content in the soil, benefiting not only themselves but also other plants growing nearby.
Does plants take in nitrogen directly from air?
NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.
How do plants and animals differ in the ways they obtain nitrogen?
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
Do most organisms use nitrogen in the form of nitrogen gas?
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
What process in the nitrogen cycle is only carried out by bacteria?
The process of nitrogen fixation is carried out by bacteria. This process involves converting atmospheric nitrogen gas into a form that can be used by plants, such as ammonium or nitrate. This is essential for making nitrogen available to the rest of the ecosystem.
