Detailed explanation-1: -Answer: Density independent factors vary based on the population, but they always affect the population similarly irrespective of its size. There are several common density independent factors, such as natural disasters, temperature, including the oxygen level in the atmosphere.

Detailed explanation-2: -There are many common density independent factors, such as temperature, natural disasters, and the level of oxygen in the atmosphere. These factors apply to all individuals in a population, regardless of the density.

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.

Detailed explanation-4: -Two density-independent limiting factors include temperature and weather. These two factors do not rely on the size or density of a certain population. They affect all organisms (in a population) equally.

Detailed explanation-5: -Wildfire is abiotic (nonliving), and most density-independent limiting factors fall in this category. Other density-independent factors include hurricanes, pollutants, and seasonal climate extremes.
