Question

In a 10 m2 ecosystem, there are 40 possums. What is the population density of possums?

02 per m2
04 per m2
010 per m2
040 per m2

Answer 1

4 possums per m^2

Step-by-step explanation:

Answer 2

The answer is 04 per m2.

This could be solved using a proportion. If 40 possums live in 10 m2, how many possums will live in 1 m2:
40 possums : 10 m2 = x possums : 1 m2
x possums = 40 possums : 10
x possums = 4 possums

So, there will be 4 possums in 1 m2 and the population density is 4 possums per m2.
