Plants cannot make protein from pure carbohydrate, because proteins contain nitrogen and sometimes sulphur. They get the nitrogen which they need from the nitrates in the soil.the bacteria called `Rhizobium `lives in the roots of legminous plants and leg. plants need nitrogen to grow pulses.The bacteria called `rhizobium` changes the atmospheric nitrogen in solution form and in return the plants give the bacteria shelter and food thus this is called a symbiotic relationship .
What else can I help you with?
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 is the most important organism in the nitrogen cycle?
Bacteria are the most important organisms in the nitrogen cycle. They play key roles in converting nitrogen in the atmosphere into forms that plants can use, and also in breaking down organic matter to release nitrogen back into the environment.
What is the difference between free nitrogen and fixed nitrogen?
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
Why is nitrogen fixation important to living things?
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
What process involves the capture and conversion of nitrogen into a form usable by plants?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
Can most organisms can use free nitrogen air?
No, most organisms cannot use free nitrogen gas from the air. Instead, certain bacteria have the ability to convert atmospheric nitrogen into a form that plants can absorb and utilize. This process is known as nitrogen fixation.
Can most organisms use the free nitrogen in air?
No, most organisms cannot use the free nitrogen in the air. Instead, certain bacteria and archaea have the ability to convert atmospheric nitrogen into a form that plants can use through a process called nitrogen fixation. This fixed nitrogen then moves through the food chain as organisms consume plants and other organisms.
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 elements are most organisms unable to take from the atmosphere?
nitrogen
Do most organisms use nitrogen directly form air?
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?
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.
Why is nitrogen fixation necessary?
Most plants use single nitrogen atoms, not N2 molecules.
What is the most important organism in the nitrogen cycle?
Bacteria are the most important organisms in the nitrogen cycle. They play key roles in converting nitrogen in the atmosphere into forms that plants can use, and also in breaking down organic matter to release nitrogen back into the environment.
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 is the difference between free nitrogen and fixed nitrogen?
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
What organisms are capable of converting gaseous nitrogen in the air into a form that other living organisms can use?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are capable of converting gaseous nitrogen in the air into a form that other living organisms can use, such as ammonia or nitrate. These bacteria form symbiotic relationships with plants, providing them with usable nitrogen in exchange for carbohydrates.
Plants use nitrogen to make?
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
