Which of the following is not a logical pairing of another environmental factor that will possibly affect the bluegill population with how that factor would affect it?

a. acid rain
b. extinction of bluegills competitor
c. pollutants
d. soil erosion

b. extinction of bluegills competitor

Explanation:

The extinction of the competitor of this species of fish will not negatively affect their populations because by decreasing competition there are more food resources and for that reason the number of bluegill increases as the number of surviving offspring will increase

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
