Ammonia. I just read that straight from the science book.
Nitrogen can form covalent bonds.
Bacteria Ammonia, nitrates, nitrites
Bacteria are the only organisms that can convert nitrogen into a usable form. Diazotroph or nitrogen-fixing bacteria are types of bacteria that perform this ability.
Humans use nitrogen in the form of proteins. Bacteria found in soil convert atmospheric nitrogen into nitrates that plants use to produce proteins.
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
Bacteria =========================== Specifically a particular type of bacteria that live in nodules on the roots of certain plants (eg the Legume family) called "Nitrogen Fixing Bacteria" . Not other bacteria decompose organic material and release nitrogen back into the atmosphere.
which of these organisms convert atmospheric nitrogen gas to a form that can be utilized by plants? a. bacteria b. protists c. consumers d. producers e. fungi
Nitrogen-fixing bacteria
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)?
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
