Question

Nitrogen-fixing bacteria make ammonia from nitrogen gas .target 1 of 4target 2 of 4 Ammonifying bacteria make amino acids from ammonium .

Answer 1

Nitrogen-fixing bacteria are found in root nodules of legumes and convert nitrogen to ammonium and organic substances.

They are released during breakdown and converted to nitrates.

How does nitrogen fixing bacteria produce ammonia?

Lightning produces only a trace quantity of ammonia. Some ammonia is also manufactured industrially by the Haber-Bosch process, which employs an iron-based catalyst, extremely high pressures, and quite high temperatures. However, bacteria in the nitrogen fixation process convert the majority of N2 into ammonia and ultimately into proteins.

Prokaryotes are all nitrogen-fixing organisms. Some of them, known as free-living nitrogen-fixing bacteria, exist independently of other species.
