Question

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density

Answer 1

Given parameters:

Number of lizards  = 150 lizards

Area of the study = 25km²

Unknown:

Population density = ?

Solution:

Population density refers to the number of organisms per area in a particular location.

Mathematically;

     Population density  = $\frac{Total Population}{Area}$  

    Population density  = $\frac{150}{25}$   = 6lizards/km²

The population density of the study area is  6lizards/km²
