Population Size and Density
Population size refers to the total number of individuals in a population (N), while population density is the number of individuals within a specific area or volume. For example, larger populations may be more stable due to higher genetic variability, while low-density populations may face challenges in finding mates. Smaller organisms tend to have higher population densities compared to larger organisms.
