although air is full of nitrogen, it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?
AMMONIA, NITRATES AND NITRITES
What else can I help you with?
Although air is full of nitrogen it is not available for organisms to readily use. What is nitrogen changed into before being used by living things?
Nitrogen gas in the atmosphere is transformed by nitrogen-fixing bacteria into ammonia or nitrate, which are forms of nitrogen that can be absorbed and utilized by plants and other living organisms.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?
Nitrogen is changed into ammonia and nitrates through the process of nitrogen fixation before being used by living things. This conversion is typically carried out by specialized bacteria in the soil or water.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances b?
Nitrogen is changed into ammonia by nitrogen-fixing bacteria in soil and water. This ammonia can then be further converted into nitrites and nitrates by other species of bacteria in a process called nitrification. These nitrates are then used by plants to make proteins and other essential molecules.
Although air is full of nitrogen it is not available for organisms to readily use nitrogen is changed into which substance before being used by living things?
Nitrogen is transformed into ammonia through a process called nitrogen fixation before it can be used by living organisms. Certain bacteria are responsible for this conversion, either through mutualistic relationships with plants or through free-living nitrogen-fixing bacteria in the soil.
Although genetic mutations may occur spontaneously in organisms the incidence of such mutations may be increased by?
Radioactive substances in the environment
How do nitrogen fixing bacteria on root nodules function in the nitrogen cycle?
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 cycle. Some nitrifying bacteria lives in the roots of legumes, and do the same job.
If nearly 79 of the atmosphere is made of nitrogen how could there be a shortage of nitrogen in soil?
Although the atmosphere is rich in nitrogen gas, plants cannot use this form directly. Nitrogen needs to be converted into a usable form like nitrates by soil bacteria for plants to uptake. In cases where the soil lacks these nitrogen-fixing bacteria or has been depleted due to overfarming, there can be a shortage of available nitrogen for plants.
What element are most living things unable to take from the biosphere?
Most living things are unable to take nitrogen directly from the biosphere in its gaseous form (N₂). Although nitrogen is abundant in the atmosphere, organisms typically require it in a fixed form, such as ammonia (NH₃) or nitrate (NO₃⁻), which can be utilized for biological processes like protein synthesis. Certain bacteria and archaea can convert atmospheric nitrogen into these usable forms through a process called nitrogen fixation, making it accessible to other organisms in the ecosystem.
Why are nitrogenous fertilizers necessary when there is nitrogen in the air?
Although nitrogen makes up about 78% of Earth's atmosphere, plants cannot use atmospheric nitrogen directly. Nitrogen gas needs to be converted into a usable form, such as ammonium or nitrate, through a process called nitrogen fixation. Nitrogenous fertilizers provide plants with this readily available form of nitrogen to support their growth and development.
Is helium one of the main chemical materials contained in organic substances?
No. The main chemicals are carbon, hydrogen, oxygen, and nitrogen. Remember the acronym CHON, although the H may confuse you. However, carbon dioxide is an exception to this rule.
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.
Is nitogen flammable?
Although nitrogen can form oxides it not flammable.
