Question

In a 10 m2 ecosystem, there are 40 possums. What is the population density of possums?
A.) 2 per m2
B.) 4 per m2
C.) 10 per m2
D.) 40 per m2

Answer 1

Hello Dear.

Here is the answer---

Answer → Option B.

Solving →

Area of the Ecosystem = 10 m².
Number of Possums = 40.

∵ Population density is the number of Peoples or animals living per unit area.

∴ Population density of the Possums = Number of Possums ÷ Area of the Ecosystem.

∴ Population Density of the Possums = 40/10
   = 4 per m².


Hence, the Population Density of the Possums is 4 per/m². Thus, Option B. is Correct.


This means that 4 Possums are living in the area of 1 m².



Hope it helps.

Answer 2

Here is the answer---

Answer → Option B.

Solution →

Area of the Ecosystem = 10 m².
Number of Possums = 40.

∵ Population density is the number of Peoples or animals living per unit area.

∴ Population density of the Possums = Number of Possums ÷ Area of the Ecosystem.

∴ Population Density of the Possums = 40/10
   = 4 per m².


Hence, the Population Density of the Possums is 4 per/m². Thus, Option B. is Correct.


This means that 4 Possums are living in the area of 1 m².
