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.

Natural ladybugs.
You can indeed use ladybugs in a pest control, but that depends on the pest. Since in the question, you don't specify what the pest is, the answer is natural ladybugs.
If the animal was something that ladybugs eat, like aphids for example, than ladybugs could be used as a pest control insect.
