In nitrogen fixation what 2 molecules are produced so that nitrogen is in a useable form?
In nitrogen fixation, two molecules are produced: ammonia (NH3) and ammonium ion (NH4+). These molecules are in a usable form for plants to uptake and utilize for growth and development.
Name two things that perform most nitrogen fixation?
Clover peas lupins.
What is nitrogen changed into before being used by living things?
Nitrogen is changed into ammonia through a process called nitrogen fixation, typically carried out by soil bacteria or certain plants like legumes. Ammonia is then converted into other forms of nitrogen such as nitrites and nitrates that are taken up by plants for growth and utilized by other living organisms in the food chain.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
How is the phosphorus cycle like the nitrogen cycle?
Their resemblance is only a fact that the ratio of Nitrogen and Phosphorus remains constant on earth. The phosphorus and nitrogen cycle both are utilized by organisms, and in order to get the required nutrients from the atmosphere.
Which organisms captures atmospheric nitrogen for the process of nitrogen fixation?
Legumes. They are the primary plant in an ecosystem, and help convert atmospheric nitrogen in nitrogen in the soil that plants can absorb through their root systems. The process is called nitrogen fixation.The organisms involved in nitrogen fixation are nitrifying bacteria like Azatobacter and Pseudomonas forming root nodules in legumenous plants.
What is meant by nitrogen fixation state two ways in which nitrogen gas of the atmosphere can be fixed in nature to get nitrogen compound in the soil?
Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.

What causes nitrogen Fixation?
nitrogen fixation is caused by the bacteria called rhizobium.
What are two ways nitrogen can be removed from the atmosphere?
Nitrogen can be removed from the atmosphere through biological processes such as nitrogen fixation by plants and bacteria, where nitrogen gas is converted into a form that can be used by living organisms. It can also be removed through industrial processes like the Haber-Bosch process, which converts nitrogen gas into ammonia for use in fertilizers and other products.
What two things can fix nitrogen?
Nitrogen-fixing bacteria and leguminous plants, such as soybeans and clover, can fix nitrogen by converting atmospheric nitrogen into a form usable by plants through a process called nitrogen fixation.
What two groups of bacteria responsible for nitrogen fixation are found in what and in the root of?
The two main groups of bacteria responsible for nitrogen fixation are Rhizobium found in legume root nodules, and Azotobacter found in the rhizosphere of various plants. Rhizobium forms a mutualistic relationship with legumes, providing fixed nitrogen in exchange for sugars, while Azotobacter functions as a free-living nitrogen fixer in the soil.
What type of organism is responsible for performing the majority of nitrogen fixation?
There are two ogranisms that are nitrogen fixers:Free-living (non-symbiotic) bacteria, which live in the soil. This includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and such genera as Azotobacter, Beijerinckia, and ClostridiumMutualistic (symbiotic) bacteria, which live live in nodules in the roots of plants. This includes Rhizobium,associated with leguminous plants, and Spirillum lipoferum,associated with cereal grasses.Nitrogen fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds that plants can use in the soil.
What are two ways by which nitrogen can combine and form nitrates?
Nitrogen can combine and form nitrates primarily through two processes: biological nitrification and atmospheric nitrogen fixation. In biological nitrification, soil bacteria convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-) through a series of oxidation reactions. In atmospheric nitrogen fixation, lightning or certain bacteria convert atmospheric nitrogen (N2) into ammonia, which can subsequently be oxidized into nitrates by soil microorganisms.
What types atoms are in ammonia?
There are two elements. They are hydrogen and nitrogen atoms.
How do living organisms obtain their nitrogen requirement?
All organisms need nitrogen to live and grow. Plants take up nitrate ions from the soil, they are then absorbed into roots by active transport, the plant then produces nitrogen-containing compounds such as protein. This nitrogen then gets into the food web as primary consumers feed on plants and obtain the nitrogen-containing compounds. However, the atmosphere is made up of 78% nitrogen and is unavailable in this form to organisms. This is due to the triple bond between the two N atoms causing it to be inert. To be used by organisms, it must be converted to a chemically available form, such as ammonium (NH4+), nitrate (NO3-), or urea ((NH3)2CO). There are five main processes that convert nitrogen to a more accessible form. They are; nitrogen fixation, nitrogen uptake, decay process, nitrification and denitrification. The first process I will talk about is nitrogen fixation. There, the nitrogen is converted to ammonium; it is the only way organisms can obtain nitrogen directly from the atmosphere. The only organism that can fix nitrogen through metabolic process is bacteria from the genus Rhizobium. The nitrogen fixers are usually found on host plants, but there are also nitrogen fixing bacteria found without host plants. They are known as free-living nitrogen fixers, e.g. in the aquatic environment a very important nitrogen fixer would be cyanobacteria. Nitrogen fixation can also be carried out in high-energy natural events, such as lightning and forest fires. The high-energy breaks the triple bond between the two nitrogen atoms producing a significant amount of single nitrogen atoms available for use. The next process is nitrogen uptake, this is where plants or bacteria itself makes use of the ammonia produced by the nitrogen fixing bacteria. The ammonium is converted from NH4+ to N to make protein or other nitrogen containing compounds. A very important process that returns nitrogen back to the nitrogen cycle for use is the decay process. When organisms, die, nitrogen is converted back into inorganic nitrogen by a process called nitrogen mineralization. Decomposers consume the organic matter and this leads to decomposition. Nitrogen contained within the dead organism in converted to ammonium, it is then available for use to plants, or transformed into NO3- (nitrification). Through the nitrogen cycle, food-making organisms obtain necessary nitrogen through nitrogen fixation and nitrification. Nitrogen compounds are returned to atmosphere and soil through decay and denitrification. In crops, few plants are left to decay back into soil, so the nitrogen cycle doesn't supply enough nitrogen to support plant growth. Therefore natural or artificial fertilizers containing NO3- or NH4+ compounds are added.
What two things can change nitrogen gas to a compound?
Nitrogen gas can be changed into a compound through nitrogen fixation, where certain microorganisms convert nitrogen gas into ammonia. It can also be combined with oxygen during lightning strikes or in high-temperature industrial processes to form nitrogen oxides.
