Question

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

Answer 1

Answer:

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 $= 10 m^{2}$

Total number of possums $= 40$

Substituting the value in equation A, we get -

$\frac{40}{10m^{2} } \\= 4 m^{2}$

Thus, option B, is correct.

Answer 2

the above answer is incorrect, i chose it. the CORRECT answer is B. hope this helps.
