In a $10 m^2$ ecosystem, there are 40 possums. What is the population density of possums?
A. 4 per $m^2$
B. 10 per $m^2$
C. 40 per $m^2$
D. 2 per $m^2
Answer (1)
Divide the number of possums by the area of the ecosystem to find the population density.
Population density = 10 40 .
Calculate the population density: 40/10 = 4 .
The population density of possums is 4 per m 2 .
Explanation
Understanding the Problem We are given that there are 40 possums in a 10 m 2 ecosystem. We need to find the population density of possums in this ecosystem. Population density is defined as the number of individuals per unit area.
Calculating Population Density To find the population density, we will divide the number of possums by the area of the ecosystem.
Performing the Calculation Population density = Ecosystem area Number of possums = 10 40 = 4 possums per m 2 .
Stating the Answer Therefore, the population density of possums in the ecosystem is 4 possums per m 2 .
Examples
Understanding population density is crucial in wildlife management and conservation. For instance, if you're studying the impact of urbanization on local wildlife, knowing the population density of a species like possums helps you assess how their habitat is being affected. A high population density might indicate overcrowding and competition for resources, while a low density could signal habitat loss or other environmental stressors. By monitoring these densities, conservationists can make informed decisions about protecting and managing wildlife populations.
