Ch 5: Prentice Hall Biology Chapter 5: Populations

About This Chapter

The Populations chapter of this Prentice Hall Biology Companion Course helps students learn essential biology lessons on populations. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Populations textbook chapter.

How it works:

  • Identify the lessons in the Prentice Hall Populations chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the populations topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Methods for calculating rate and exponential growth
  • Factors that affect human population size
  • Density and survivorship in populations
  • Interspecific competition and competitive exclusion
  • Niche differentiation
  • Carrying capacity of a population
  • Migration and dispersion
  • Biotic potential of a population
  • Characteristics of populations in highly developed and developing countries

Calculating Rate and Exponential Growth: The Population Dynamics Problem

1. Calculating Rate and Exponential Growth: The Population Dynamics Problem

You know how the world population keeps increasing? It's increasing faster now than it was 100 or 1,000 years ago. In this lesson, learn how differential equations predict this type of exponential growth.

The Human Population: Factors that Affect Population Size

2. 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.

Populations: Density, Survivorship and Life Histories

3. 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.

Interspecific Competition, Competitive Exclusion & Niche Differentiation

4. Interspecific Competition, Competitive Exclusion & Niche Differentiation

What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.

Carrying Capacity, Migration & Dispersion

5. 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.

Biotic Potential and Carrying Capacity of a Population

6. 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.

Population Characteristics of Highly Developed & Developing Countries

7. 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.
