III only (floods and drought) is an example of density-independent factor affecting population growth.
<h3>WHAT IS DENSITY-INDEPENDENT FACTOR?</h3>
Certain factors affect the growth and multiplication of living organisms in populations. These factors can either be;
- Density-dependent
- Density-independent
Density-independent factors are those factors that are not dependent on the density of the population to affect them. These factors are usually physical factors of the environment like;
- Disasters
- Flood and drought
- Earthquake etc.
Therefore, III only (floods and drought) is an example of density-independent factor affecting population growth.
