The answer is 6 per m2.

A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons

Thus, the population density is 6 raccoons per m2.

Answer:

The correct answer is option A, \(6\frac{Racoons}{m^2}\\\)

Explanation:

The Population density of any species in an ecosystem is equal to the number of that species living in one unit of area.  

Thus , population density can be represented as  

\(\frac{Total population }{Total area of habitat} \\\)

Substituting the given values in above equation, we get -

\(= \frac{60}{10} \frac{Racoons}{m^2}\\= 6 \frac{Racoons}{m^2}\\\)
