Question

The algae, walleye pollock, and orca populations could have all affected the moon jelly population. What additional evidence do you need to determine which of these populations might have caused the size of the moon jelly population to increase?

Answer 1

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..

Explanation:

Answer 2

Answer:

• 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.
