Density-independent factor | Biology, Definition, & Examples
https://www.britannica.com/science/density-independent-factor
WebDensity-independent factor, any force that affects the size of a population of living things regardless of the density of the population. They often arise from physical and chemical (rather than biological) phenomena. Examples include weather and climate phenomena and natural disasters.
