1. Biotic Potential and Carrying Capacity of a Population
When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.
2. Populations: Density, Survivorship and Life Histories
Have you ever wondered how biologists determine the populations of animals in a particular geographic area? Watch this video lesson to find out, and discover how scientists look at the survivorship and life histories of many different species.
3. Carrying Capacity, Migration & Dispersion
Have you ever wondered why some types of birds fly south in the winter or why some animals form territories? Watch this video to learn about a species' maximum growth capabilities, the way its members group themselves and why they might migrate to new locations every year.
4. Dispersal, Colonization, and Island Biogeography
Have you ever gone in your backyard and discovered a wild raspberry bush that has never been there before? How did it get there? Why is there only one bush year after year? In this lesson, you'll study how plant and animal species colonize in new areas through dispersal and immigration and how some species thrive in a new area while others fail.
5. The Human Population: Factors that Affect Population Size
The human population is constantly changing. In this lesson, we will explore the factors that cause increases and decreases in the human population, including births, deaths, immigration, and emigration.
6. Thomas Malthus' Theory of Human Population Growth
In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.
7. Poverty, Carrying Capacity, Population Growth & Sustainability
Worldwide poverty is a large issue. In this lesson, we will explore how poverty influences population growth rates and how these things relate to carrying capacity and global sustainability.
8. What Is Demographic Transition? - Definition & Stages
There are many differences between non-industrial and industrial countries. In this lesson, we will explore the concept of demographic transition and the stages that guide a country through its changes into an industrial country.
9. Population Characteristics of Highly Developed & Developing Countries
The population of a country is based on many factors. In this lesson, we will explore several important factors that differ between developed and developing countries.
