A big, dense population is more influenced than a small, sparsely populated area. Different species populations in the same ecosystem will be affected differently. Beginning with a population size where space and food are not limiting, the population grows rapidly in an exponential pattern; at a certain population density, population growth slows and stabilizes at a given carrying capacity. Food, and other usable biological resources, are density dependent. In population ecology, limiting factors are factors in the environment that control various aspects of a population. However the main factor is the availability of food. Density-dependent factors include competition, predation, parasitism and disease. Consider the sunlight as a resource for the plants.
