The Nutrient Quiz

The two forms of dissolved inorganic nitrogen in water are nitrate and ammonium.

Nitrogen fixation is the process of converting atmospheric nitrogen (N2 gas) into a usable form by certain bacteria, such as cyanobacteria and archaea. It is done by the nitrogenase enzyme and is highly energy consuming.

The organic forms of nitrogen mentioned in the text include amino acids, nucleic acids, proteins, and urea.

<p>Heterocysts in cyanobacteria are specialized cells for nitrogen fixation. They provide an anaerobic environment for nitrogenase activity and are essential for the process of nitrogen fixation.</p> Signup and view all the answers
