Detailed explanation-1: -Density-independent limiting factors affect all populations in similar ways, regardless of population size and density. Unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires, can act as density-independent limiting factors.

Detailed explanation-2: -The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution. The chances of dying from any of these limiting factors don’t depend on how many individuals are in the population.

Detailed explanation-3: -What is drought a density-independent limiting factor? drought will affect a population in the same way regardless of the population’s size or density.

Detailed explanation-4: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
