Population growth in ecological systems is regulated by a variety of factors that can be broadly divided into density-dependent and density-independent factors. Density-dependent factors are those whose effects on a population vary with population density. As the number of individuals increases, competition for resources such as food, water, and shelter intensifies, leading to reduced survival and reproduction. Predation is another example, as predators often have more access to prey when the prey population is abundant. Similarly, __________ _______ ___ _____ ______.
