Exciting Facts about Population Growth and Factors Affecting It!

What is an example of a density-independent factor for population growth?

a. Fire

b. Predators

c. Competition for nesting sites

d. Food availability

Answer:

The correct answer is 'a. Fire,' which is an example of a density-independent factor affecting population growth since it impacts populations irrespective of their density.

An example of a density-independent factor for population growth would be 'a. Fire.' This is because environmental conditions like fire affect populations regardless of their density. Fires will have an impact on a population whether it is large or small, thus not influenced by population density. In contrast, density-dependent factors such as predation, competition for nesting sites, and food availability are influenced by the population density. For instance, the effect of predators or competition for resources becomes more pronounced as population density increases.
