Patterns of Population Growth in an Ecosystem | Sciencing
The birth rate minus the death rate with no environmental restrictions defines a species intrinsic growth rate. Within an ecosystem, however, resource limits and predation also effect population growth. There are four main patterns of population growth: J-pattern, logistical growth, temporally fluctuating and predator-prey interaction.

A human population will achieve zero population growth if couples have an average of about 2 children each (to account for some children who do not survive to reproduce). If a population has a birth rate of 40 individuals per 1,000 per year and a death rate of 30 individuals per 1,000 per year, how will the population change each year?[PDF]

Patterns of Human Population Growth Demography is the scientific study of human populations. Demographers try to predict how human populations will change over time. Over the past century, population growth in developed countries slowed. As death rates dropped, birthrates dropped also. Demographers call this shift the demographic transition. Most people live in countries that have not [PDF]

answer this question, population biologists study the factor that determines population growth—an organism’s reproductive pattern, also called its life-history pattern. A variety of population growth patterns are possible in nature. Two extremes of these patterns are demon-strated by the population growth rates of mosquitoes and elephants.[PDF]

logistic growth patterns result from births, deaths, immigration, and emigration. SAMPLE ANSWER: Predation, disease, and other factors slow or stop population growth. SAMPLE ANSWER: Density-dependent factors that limit population growth include competition, predation, herbivory, parasitism, disease, and overcrowding. Density-[PDF]
