Bacteria are the primary organisms that convert nitrogen into a form usable for humans through a process called nitrogen fixation. Certain bacteria, such as those in the genus Rhizobium, form symbiotic relationships with plants, while others, like free-living nitrogen-fixing bacteria, can convert atmospheric nitrogen into ammonia. Algae can also play a role in nutrient cycling, but they do not directly fix atmospheric nitrogen to the same extent as bacteria.
A. Bacteria are the primary organisms that fix nitrogen into forms like ammonia. Certain bacteria, including those in the genera Rhizobium and Frankia, perform this process either in symbiotic relationships with plants or independently in the soil. While some algae also have the capability to fix nitrogen, it is predominantly bacteria that are recognized for this essential ecological function. Humans and plants do not fix nitrogen.
"Positive organisms" is a term that typically refers to microbes that have beneficial effects on their environment, such as by promoting health or growth in plants, animals, or humans. Examples include probiotic bacteria in the gut that aid in digestion or nitrogen-fixing bacteria in soil that enhance plant growth.
Nitrogen metabolism refers to the biochemical processes through which organisms convert nitrogen from various sources into usable forms, primarily for the synthesis of amino acids, nucleotides, and other nitrogen-containing compounds. This process includes nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by certain bacteria, as well as the assimilation and dissimilation of nitrogen in plants and animals. In humans and other animals, nitrogen metabolism is crucial for the breakdown of amino acids and the excretion of nitrogenous waste, primarily in the form of urea. Overall, nitrogen metabolism is essential for maintaining cellular function and supporting growth and development.
False not all
Prokaryotic one-celled organisms are called bacteria. They are characterized by their simple cellular structure, lacking a nucleus and membrane-bound organelles. Bacteria can be found in various environments and play essential roles in ecosystems, such as decomposers and nitrogen fixers. Some bacteria can also be pathogenic, causing diseases in humans, animals, and plants.
Nitrogen-fixing bacteria are the organisms that convert atmospheric nitrogen into a form that is usable by plants, which in turn are consumed by humans as food. Legumes such as peas, beans, and clover have a symbiotic relationship with these bacteria, allowing them to convert nitrogen into a usable form for plants.
Bacteria Ammonia, nitrates, nitrites
Well, darling, those nitrogen-fixing bacteria are the real MVPs when it comes to converting nitrogen into a form us humans can actually use. They work their magic in the soil, taking that atmospheric nitrogen and transforming it into a more accessible form for plants to slurp up. So, next time you enjoy some tasty veggies, just remember to thank those little bacteria for doing all the hard work behind the scenes.
Certain bacteria, such as those in the genera Rhizobium and Azotobacter, convert atmospheric nitrogen (N₂) into ammonia (NH₃) through a process called nitrogen fixation. This ammonia can then be further transformed into nitrites (NO₂⁻) and nitrates (NO₃⁻) by other bacteria in the soil. While these nitrates can be taken up by plants, which humans consume, nitrogen itself in its gaseous form is not usable by humans without this conversion process.

Micro organisms refer to microscopic creatures, such as bacteria. Humans are not among which.
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)?
Humans are more complex organisms.

Humans use nitrogen primarily in the form of fertilizers for agricultural purposes to promote plant growth. Nitrogen is also used in the production of ammonia for various industrial applications such as making explosives, cleaning products, and refrigerants. Additionally, nitrogen gas is used in the food packaging industry to preserve freshness and prevent spoilage.
