Question

In August 2005, Hurricane Katrina caused significant damage in several states along the Gulf Coast, including Alabama, Mississippi, and Louisiana. Thousands of people were evacuated from their homes due to flooding and other damage that was caused by the storm. Which type of limiting factor was Hurricane Katrina?
density-independent factor
density-dependent factor
population-dependent factor
population-independent factor

Answer 1

The answer is Density-independent.

Answer 2

The correct answer is a density-independent factor.  

Density-independent factor refers to any factor that restricts the population size, and whose influence is not reliant on the number of people in the population. An example of such a factor is a hurricane that will eradicate or kill all the individuals of the population, which comes under its influence irrespective of whether the size of the population of large or small.
