Density Independent Factor
Density independent factor explained in an easy to understand way:
Imagine trying to plan an outdoor picnic, only to have it suddenly rained out. Just as a rainstorm disrupts your picnic plans regardless of how many people are attending, a cold climate can limit population growth independently of how large or small the population is. In both cases, the external factor—rain for your picnic and cold climate for population growth—affects the outcome regardless of other variables like the number of attendees or population size, highlighting how certain environmental conditions can play a decisive role irrespective of internal factors.

Density Independent Factor: A factor that limits population growth independent of population size, for example, a cold climate, is a density-independent factor. In science, a density-independent factor affects a population's growth regardless of how many individuals are in the population.
