In a 10 m2 ecosystem, there are 40 possums. what is the population density of possums? 2 per m2 4 per m2 10 per m2 40 per m2

Option B, 4 per m2

Explanation:

The population density of any species or human is the number of species or human beings living in a unit area.

Thus population density can be represented mathematically as

Population density Number of species/Human beings in a given region Area of the region ----------------Eq (A)

Given -

Area of the ecosystem

Total number of possums

Substituting the value in equation A, we get -

Thus, option B, is correct.
