NEET BIOLOGY

Detailed explanation-1: -Density-independent limiting factors do not depend on population size. They include unusual weather, natural disasters, seasonal cycles, and human activities such as damming rivers. In response to such fac-tors, many species have a rapid drop in population size.

Detailed explanation-2: -Density-independent factors are limiting factors that include things like unusual weather, natural disasters, and human activity.

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: -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.
