What does the abyssopelagic gets its energy and nutrients from?

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. "Abyss" ... This region also contains a much higher concentration of nutrient salts, like ... Many animals also move very slowly to conserve energy. Their reproduction rates are also very slow, to decrease competition and conserve energy.

Explanation:

Rather than relying on producers to form the base of the food pyramid, organisms living in the abyssal zone must feed on the dead organic detritus that falls from oceanic layers above. ... For example, many of these organisms convert hydrogen sulfide to sulfate to produce chemical energy.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
