If 40 carabaos live in a 4 sq. meter area, what is their population density per sq. km.?

Explanation:

Given parameters:

Number of carabaos = 40

Area of the place = 4m²

Unknown:

Population density  = ?

Solution:

The population density of the place is the number of organisms per square km.

 Mathematically;

       Population density  =  

   Population density  =   = 10carabaos/m²

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)
