Question

density is divided into which two factors? immigration and emigration fertility and fecundity independent and dependent biotic and abiotic

Explanation:

In population ecology, factors affecting population density are categorized into density-dependent (factors whose impact changes with population density, like competition) and density-independent (factors whose impact is not tied to population density, like natural disasters). The other options describe different population-related concepts: immigration/emigration are movement factors, fertility/fecundity relate to reproduction, and biotic/abiotic are broad ecosystem factors, not the two divisions of density factors.

Answer:

independent and dependent
