What form of nitrogen do plants most easily use for their growth and development?
Plants most easily use nitrate (NO3-) as the form of nitrogen for their growth and development.
What form of nitrogen do plants most easily use, and can they utilize any other form Why or why not?
Plants most easily use nitrate form of nitrogen. They can also use ammonium form, but nitrate is preferred because it is more readily available in soil and easier for plants to absorb.
In what form most organisms obtain nitrogen?
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.
What kind of bacteria annually save farmers millions of dollars in fertilizer costs?
Bacteria which are part of the Rhizobia family can "fix" nitrogen in the soil when living in a symbiotic relationship with a legume (Fabaceae) plant. The bacteria live in nodules which form on the roots of the plants, converting atmospheric nitrogen into a plant-usable form which is left in the soil for the next crop. Nitrogen is the most-needed crop nutrient of all the fertilizers, and is frequently the most expensive fertility cost for the farmer.
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.
What is the usable form of nitrogen that is found in the ground?
Nitrate (NO3-) is the most common usable form of nitrogen found in the ground and is readily absorbed by plants for growth and development.
What is the large reservoir of nitrogen that is unusable by most organisms?
The large reservoir of nitrogen that is unusable by most organisms is atmospheric nitrogen (N2). This form of nitrogen is inert and cannot be directly utilized by plants and animals. It needs to be converted into a usable form through the process of nitrogen fixation before it can be incorporated into biological molecules.
Even though considerable nitrogen is available in the air most plants do not use the nitrogen in the air why not?
Plants cannot directly use nitrogen gas (N2) from the air because they lack the enzymes required to convert N2 into a form (like ammonia or nitrates) that they can assimilate. Therefore, plants rely on nitrogen-fixing bacteria in the soil to convert atmospheric nitrogen into a usable form. This nitrogen fixation process allows plants to obtain the necessary nitrogen for growth and development.
What organism is responsible for converting nitrogen into nitrates?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are responsible for converting atmospheric nitrogen into nitrates through a process called nitrogen fixation. These bacteria can be found in the soil and form symbiotic relationships with plants to provide them with usable forms of nitrogen.
What form of nitrogen do plants most easily use for their growth and development?
Plants most easily use nitrate (NO3-) as the form of nitrogen for their growth and development.
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 part of the nitrogen cycle is most responsible for making nitrogen available for plants?
The process of nitrogen fixation is most responsible for making nitrogen available for plants. This is when certain bacteria in the soil or in the roots of leguminous plants convert atmospheric nitrogen into a form that can be taken up by plants as nutrients.
What form of nitrogen do plants most easily use, and can they utilize any other form Why or why not?
Plants most easily use nitrate form of nitrogen. They can also use ammonium form, but nitrate is preferred because it is more readily available in soil and easier for plants to absorb.
How do most plants meet their nitrogen needs?
Most plants meet their nitrogen needs by absorbing nitrate and ammonium ions from the soil through their roots. Some plants also form symbiotic relationships with nitrogen-fixing bacteria, which convert atmospheric nitrogen into a form that plants can use. This process is important for plant growth and development.
What form for nitrogen is unusable by most organisms?
Nitrogen gas (N2) is unusable by most organisms because they lack the ability to convert it into a usable form like ammonia (NH3) or nitrate (NO3-). This process, known as nitrogen fixation, is carried out by certain bacteria and archaea.
In what form most organisms obtain nitrogen?
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.
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.
