Habitat is density-dependent

a hurricane is density-independent

Hunting by humans is density-independent

Industrial pollution is density-dependent

The above limiting factors shows some density-dependent while one is density-independent. Food, habitat, and industrial pollution all depends on population as the lesser the population the smaller the limiting factors caused while hurricane and hunting by humans are density-independent.

Food, Habitat, Number of mates, and industrial pollution are all limiting factors that solely depends on density as the increase in density affects it greatly while hurricane and hunting by humans has nothing to do with increase or decrease in density, hence, they are density-independent
