Answer 1

Answer: The appropriate information that will be used to fill the blanks includes the following respectively:

-1.7

- increased

-70%

- 0.5

- decreased

- 50%

Explanation:

The green (topmost) data point at June 2011 shows a proportional change of about 1.7, which means that the native fish population INCREASED by about 70 percent when 95 percent of the lionfish were removed. In contrast, the orange data point at June 2011 shows a proportional change of about 0.5, which means that the native fish population DECREASED by about 50 percent when only a quarter of the lionfish were removed (a result that was almost the same as when none of the lionfish were removed).

The native fishes are being haunted by the lion fish, from the results, removing just few of the invasive lion fish will not make a difference. In other to help the native fish survive, many of the lion fish has to be removed.
