Question

Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor waters?

Answer 1

Answer:

The answer is Trichodesmium is an important source of usable nitrogen in the nutrient-poor waters and represents almost half of the nitrogen fixation in marine systems.

Explanation:

Nitrogen fixation is the process of converting atmospheric diatomic nitrogen into biologically usable forms of nitrogen, such as ammonium oxides and nitrogen. Trichodesmium is the only known diazotropic capable of fixing nitrogen in daylight in aerobic conditions, being the main diazotropic in marine pelagic systems and an important source of usable nitrogen in the nutrient-poor waters where it lives. Trichodesmium fixes nitrogen on a scale that represents almost half of the nitrogen fixation in marine systems worldwide.

Answer 2

Cyanobacteria convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere
