Impact of Forest Fire on Population Growth

What is a density-independent limiting factor that affects population growth? Final answer: A forest fire is a density-independent limiting factor that impacts population growth regardless of the population's density.

Understanding Density-Independent Limiting Factors

Density-independent limiting factors refer to environmental conditions that affect a population's growth and numbers irrespective of its density. This distinguishes them from density-dependent factors, which vary based on the population density.

Examining the List of Factors

Among the given options - forest fire, limited food supply, number of nesting sites, and infectious diseases - the example of a forest fire stands out as a density-independent limiting factor. Forest fires impact populations regardless of their density because they destroy habitats indiscriminately.

Conclusion

Understanding the distinction between density-independent and density-dependent limiting factors is crucial in assessing their impact on population growth. By recognizing the role of factors like forest fires, we can better grasp the complexities of ecological dynamics.
