Answer 1

the answer is D i just took the test 

Answer 2

Answer: the correct choice is d) 100000 organisms in 0.5 miles.

Explanation: Population density is directly proportional to the number of species(organisms) and inversely proportional to the land area.

population density = number of organisms/land area

Let's plug in the values for all the choices and see which one gives greatest population density.

a) population density =
`(125000)/(2.5)` = 50000

b) population density =
`(13000)/(1.0)` = 13000

c) population density =
`(150000)/(4.0)` = 37500

d) population density =
`(100000)/(0.5)` = 200000

From above calculations, the greatest population density(200000 organism per mile) is for the last choice.

So, the correct choice is d) 100000 organisms in 0.5 miles.
