When an atom or molecule gains one or more electrons, it is said to bea. reducedb. polarizedc. oxidizedd. energized

Ƒ An atom that gains one or more electronswill have a NEGATIVE charge. ƒ An atom that loses one or more electrons will have a POSTIVE charge. ƒ An atom that gains or losesone or more electrons is called an ION. ƒ A positive ion is called a CATION and a negative ion is called an ANION.

From this information above you can see its negative so it means it gets reduced
hope it helped

In this reaction the lead atoms gain anelectron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced
and as you can see oxidation only happens when oxygen is reduced

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
