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.
A- when the atoms covalently bond, the two hydrogens share an electron with the oxygen. As a result, they both acquire the ‘noble gas’ rank of having a full out energy shell (8 valence electrons).
His work inspired Darwin's ideas of natural selection. Lamarck also came up with an explanation for vestigial structures. His evolutionary theory was rooted in the idea that life started out very simple and developed over time into the complex human form
