Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia by certain bacteria. Ammonification, on the other hand, is the process by which organic nitrogen from dead organisms or waste is converted into ammonia by decomposers like bacteria and fungi. Nitrogen fixation introduces new nitrogen into the ecosystem, while ammonification recycles existing nitrogen.

Differences between nitrogen fixation and phosphorus fixation?
Nitrogen fixation is a biochemical process that transfer atmospheric nitrogen (N2) into NH3. The former is bio-unavailable, while the later one is bio-available. There is no analogy process for phosphorus.
What is the difference between nitrogen-14 and nitrogen-16?
The main difference between nitrogen-14 and nitrogen-16 is their atomic mass. Nitrogen-14 has 7 protons and 7 neutrons in its nucleus, while nitrogen-16 has 7 protons and 9 neutrons. This results in nitrogen-16 being slightly heavier than nitrogen-14.
What is difference between nitrification and ammonification?
Ammonification is conversion of peptides, amino acids, and nucleic acids into ammonia in the form of NH3. It's done by microorganisms such as Bacillus spp., Proteus spp., and Pseudomonas spp. and usually takes place in soil. It can be either an oxidative or reductive process. Nitrification is the conversion of ammonia in the form of NH4- to NO3- through a two-stage process both involving the addition of oxygen (oxidation). Nitrification 1 converts NH4- to NO2- by ammonium oxidising bacteria e.g. Nitrosomonas spp. Nitrification 2 converts NO2- to NO3- by nitrite oxidising bacteria e.g. Nitrobacter spp..
Is it true that the process of combining nitrogen with other elements in order to make usable compounds is called the nitrogen cycle?
No, the process of combining nitrogen with other elements to make usable compounds is not called the nitrogen cycle. The nitrogen cycle refers to the natural processes by which nitrogen is converted between its various chemical forms in the environment, including nitrogen fixation, nitrification, and denitrification.
Is there any difference between C2H5O2N and NC2O2H5?
Yes, there is a difference between C2H5O2N and NC2O2H5. In C2H5O2N, the nitrogen atom is connected to two oxygen atoms, whereas in NC2O2H5, the nitrogen atom is connected to a carbon atom (denoted by the prefix "N"). This difference alters the chemical structure and properties of the molecules.
What is the main difference between denitrification and the other three steps of the nitrogen cycle?
The main difference between denitrification and the other three steps of the nitrogen cycle—nitrogen fixation, nitrification, and ammonification—is that denitrification converts nitrates and nitrites back into nitrogen gas (N₂), returning it to the atmosphere. In contrast, the other steps involve the transformation of atmospheric nitrogen into usable forms (nitrogen fixation), the conversion of ammonia to nitrates (nitrification), and the breakdown of organic nitrogen back into ammonia (ammonification). Denitrification thus plays a crucial role in regulating nitrogen levels in ecosystems by closing the nitrogen cycle.
What process is not part of the nitrogen cycle?
Photosynthesis is not part of the nitrogen cycle. The nitrogen cycle involves processes such as nitrogen fixation, nitrification, denitrification, and ammonification, which contribute to the cycling of nitrogen between living organisms and the environment. Photosynthesis is a process by which plants and some bacteria convert carbon dioxide and water into glucose using sunlight as an energy source.
What is the reservoir of the nitrogen cycle?
The primary reservoirs of the nitrogen cycle are the atmosphere, which contains about 78% nitrogen gas (N₂), and the soil, where nitrogen exists in various forms such as ammonium (NH₄⁺), nitrate (NO₃⁻), and organic nitrogen compounds. Additionally, nitrogen is found in living organisms as part of amino acids, proteins, and nucleic acids. The cycle involves processes like nitrogen fixation, nitrification, denitrification, and ammonification that transform nitrogen between these reservoirs.
What is the difference between symbiotic and asymbiotic nitrogen fixation?
Symbiotic nitrogen fixation occurs when nitrogen-fixing bacteria form a mutually beneficial relationship with plants, typically within nodules on plant roots. Asymbiotic nitrogen fixation, on the other hand, happens in free-living bacteria in the soil or water that can fix nitrogen without the need for a specific plant host.
Differences between nitrogen fixation and phosphorus fixation?
Nitrogen fixation is a biochemical process that transfer atmospheric nitrogen (N2) into NH3. The former is bio-unavailable, while the later one is bio-available. There is no analogy process for phosphorus.
What relationship exists between the bacteria in the soil and legume root in nitrogen fixation?
Gass
Does most nitrogen fixation use the energy released by lighting?
Nitrogen fixation is the conversion of atmospheric Nitrogen gas (N2) into Ammonia, and Nitrates that can be used by plants.Much of the nitrogen fixation is done by a symbiotic relationship between nitrogen fixing bacteria and various plants.Thus, the bacteria are not directly doing photosynthesis. The plants do the photosynthesis, and the bacteria are able to get the secondary energy from the plants and plant material.
Root nodules are associations between bacteria and plant roots responsible for?
Root nodules are associations between bacteria (such as rhizobia) and plant roots that are responsible for nitrogen fixation. The bacteria convert atmospheric nitrogen into a form that the plant can use, helping the plant to grow in nitrogen-deficient soils. This symbiotic relationship benefits both the plant and the bacteria.
What are nif and nod genes?
Nif and nod genes are involved in nitrogen fixation by certain bacteria. Nif genes are responsible for encoding proteins involved in the nitrogen fixation process, while nod genes are involved in nodulation, which is the formation of specialized structures on plant roots where nitrogen-fixing bacteria reside. These genes play essential roles in the symbiotic relationship between plants and nitrogen-fixing bacteria.
What does the nitrogen cycle include?
The nitrogen cycle includes processes such as nitrogen fixation, nitrification, assimilation, and denitrification. These processes work together to convert nitrogen between different forms that can be used by living organisms in ecosystems.
What is the difference between nitrogen and the carbon?
Nothing
What is the difference between heterocyst from hormogonia?
heterocyst is thick walled yellowish cell in cynaobacteria. it is involved in nitrogen fixation processes.cynaobacteria with sufficicent heterocysts are found symbiotically associated wuth leguminosae plants. hormogonia are cells releasedby hetercyst at time of division or fragmentation for the formation of new cynaobacteria.
