Limiting Factors
DENSITY-INDEPENDENT [exert their influences on population size regardless of the population's density(i.e. weather and climate)]:
Lack of rainfall and forest fires are two factors of density-independent factors. Both do not depend on the size of a population of organisms inhibiting the biome, which is why they are both independent.
DENSITY-DEPENDENT [effects on the size or growth of the population vary with the population density]:
Parasitism and predation are two factors that depend on the size of a population of organisms residing in the savanna biomes, which is why they are dependent.
