Explanation:
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 = 
Population density = 
= 6lizards/km²
The population density of the study area is 6lizards/km²
Answer:
