© Pearson Education,
Inc., publishing as Pearson Prentice Hall. 43 Name____________________________ Class__________________ Date __________ Chapter 5 Populations Three important characteristics of a population are geographic distribution, density, and growth rate. • Geographic distribution, or range, is the area in which a population lives. • Population density is the number of individuals per unit area. An example is the number of people per square kilometer. • Growth rate is how quickly a population increases or decreases in size. Three factors can affect population size: the number of births, the number of deaths, and the number of individuals that enter or leave the population. Populations increase through births and immigration. Immigration is the movement of individuals into an area. Populations get smaller through deaths and emigration. Emigration is the movement of individuals out of an area. Exponential growth occurs when members of a population reproduce at a constant rate. This growth pattern is shown by a J-shaped curve. As the population grows, the number of reproducing members keeps rising. Thus the population grows faster and faster. Under ideal conditions with unlimited resources, a population will grow exponentially. In nature, exponential growth does not go on for long. Resources are used up in time. This causes population growth to slow or stop. Predators and disease also slow exponential growth. As resources become less available, the growth of a pop- ulation slows or stops. This is called logistic growth. Logistic growth is shown by an S-shaped curve. Logistic growth occurs when a population’s growth slows or stops following a period of exponential growth. For example, if food resources start to run out or space becomes limited, a population that was growing exponentially may start to exhibit logistic growth. The population size when growth stops is called carrying capacity. Carrying capacity is the number of individuals of a specific species a given environment can support.

__________ 5–2 Limits to Growth A limiting factor is anything that slows population growth. There are two kinds of limiting factors. • Density-dependent limiting factors rely on population size. They include competition, predation, parasitism, and disease. Competition occurs when organisms are using the same ecological resource at the same time. Predation occurs when one organism captures and feeds on another organism. The organism that gets eaten is the prey. The organism that eats the prey is the predator. Predator-prey relationships can affect the size of both the predator population and the prey population. For example, a decrease in the prey population will be followed, sooner or later, by a decrease in the predator population. • Density-independent limiting factors do not rely on population size. They include natural disasters and human activities such as damming rivers. When such factors occur, many species show a rapid drop in population size. 5–3 Human Population Growth The size of the human population tends to increase with time. For most of human existence, the population grew slowly. About 500 years ago the population began growing faster. Agriculture and later industry made food more available. Improved sanitation and medicine reduced death rates. However, birthrates stayed high in most places. This led to exponential growth. Today, the human population continues to grow exponentially. Demography is the scientific study of human populations. Demographers try to predict how human populations will change over time. Birthrates, death rates, and the age structure of a population help predict why some countries have high growth rates while other countries grow more slowly. Over the past century, population growth in the United States, Japan, and much of Europe slowed greatly. Demographers call this shift a demographic transition. The transition began as death rates fell, causing a brief rise in population growth. Then birthrates fell, slowing population growth. Most people live in countries that still have high population growth. Demographers use age-structure diagrams to help predict population growth. An age-structure diagram is a bar graph. It shows how many people of each gender are in each age group in the population. To predict how world population will change, demographers need to think about the age structure of each country as well as the number of people with fatal diseases, including AIDS. © Pearson Education, Inc., publishing as Pearson Prentice Hall. 44
