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.(<u>Generally, Moon jelly survives under little oxygen concentration</u>.) 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..
There is a balance of resources, shelter, and number of species inside the region which is under consideration. While, the moon jelly's population may increase due to lack of presence of the competition for the resources that are present by means of other consumers of zooplankton that would enhance the growth of the moon jelly's.
Along, with that the decrease in the number of predators which are mainly the big marine animals inside the region that would increase the level or growth of the moon jelly's.
The wood has the most friction because the final speed is less than the others when the fan is on and the cart slowed down the fastest when the fan is turned off.
In this scenario,I guess the answer is roughly around 300 children die every year from the diseases in which the vaccinations are available. Hope this is the correct answer then and would surely be of big help to you then.
