Answer:
The Algae boom, which results from Eutrophication, affects the oxygen balance of the aquatic ecosystem. As the population of algae increases they consume available oxygen in the water denying predators of moon jelly oxygen for survival therefore casing their deaths,while increasing moon jelly population.(Generally, Moon jelly survives under little oxygen concentration.) These algae eventually died and settle to to the ocean bed to be decomposed by decomposers.
These bacteria make use of the available oxygen in the water, for decomposition.Thus further depleting the aquatic predators of moon jelly of available oxygen leading to their death, while allowing rapids population growth of Moon jelly..
