Density-independent factors tend to be catastrophic events. These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as ... Density-dependent factors are environmental influences that depend on population size or density, such as competition for resources, predation, and disease.
