Detailed explanation-1: -Density-independent factors are those that are not directly related to the population size, but that can still have a significant impact on it. For example, a severe drought might reduce the population size of a region, even if the population was otherwise growing.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area).

Detailed explanation-5: -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.
