GinnyAnswer

Final answer:

Nitrogen fixation is the conversion of atmospheric nitrogen into ammonia by specific bacteria, essential for organic molecule formation. Diazotrophs are crucial in providing fixed nitrogen independently, aiding various organisms. The nitrogen cycle encompasses nitrification, denitrification, ammonification, and nitrogen fixation processes.


Explanation:

Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), making it accessible to plants. This is crucial as nitrogen is an essential component of organic molecules.

Diazotrophs are bacteria and archaea capable of nitrogen fixation without relying on external fixed nitrogen. They play a key role in providing fixed nitrogen to various organisms.

Nitrogen cycle involves processes like nitrification, denitrification, ammonification, and nitrogen fixation, ensuring the continuous circulation of nitrogen in ecosystems.
