Respuesta :

the answer is D i just took the test 

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 = [tex]\frac{125000}{2.5}[/tex]  = 50000

b) population density = [tex]\frac{13000}{1.0}[/tex]  = 13000

c) population density = [tex]\frac{150000}{4.0}[/tex]  = 37500

d) population density = [tex]\frac{100000}{0.5}[/tex]  = 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.
