Ch 20: MTLE Life Science: Population & Species Diversity

About This Chapter

The lessons in our Population & Species Diversity chapter examine the factors in an ecosystem that impact its ability to support population growth. Use the material included here as part of your review plan for the MTLE Life Science test.

MTLE Life Science: Population & Species Diversity - Chapter Summary

Reexamine the diversity of living things, their concentration in a given ecosystem, how that ecosystem supports them and why they move from one place to another in these lessons. These lessons will have you ready for MTLE Life Science test questions about:

  • What the carrying capacity of a population is
  • Definitions for migration and dispersion
  • The population growth formula
  • Biotic and abiotic factors in an ecosystem
  • Primary and secondary succession
  • The significance of species diversity

Studying for an exam becomes easy, convenient and fun using this well-designed refresher chapter. The longest lesson lasts for less than ten minutes, so your progress through the course is rapid and efficient. The timeline feature enables you to study selectively by allowing you to skip sections that are already familiar to you, and the dashboard provides you with a convenient place to keep track of your work.

Carrying Capacity of a Population: Definition & Explanation

1. Carrying Capacity of a Population: Definition & Explanation

As population size increases, so does the demand for resources. Carrying capacity helps define the appropriate size of a population based on its environment. The availability of resources has a direct effect on how quickly and how large a population can grow.

Carrying Capacity, Migration & Dispersion

2. 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.

Calculating Rate and Exponential Growth: The Population Dynamics Problem

3. 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.

What is Biotic? - Definition, Factors & Examples

4. What is Biotic? - Definition, Factors & Examples

In this lesson you will learn about the biotic components in an ecosystem and the biotic factors that affect organisms. You will also have a better understanding about why planet Earth is a pretty special place.

Abiotic Factors of an Ecosystem: Definition & Examples

5. Abiotic Factors of an Ecosystem: Definition & Examples

When it comes to ecosystems, a mountain, a river, and a cloud have more in common than you might think. Abiotic factors have specific and important roles in nature because they help shape and define ecosystems.

What Is Primary Succession? - Definition & Examples

6. What Is Primary Succession? - Definition & Examples

Changes occur all over the world every day. In ecology, changes in the types of organisms that inhabit an area over time is called succession. In this lesson, we will investigate primary succession.

What Is Secondary Succession? - Definition, Examples & Stages

7. What Is Secondary Succession? - Definition, Examples & Stages

In this lesson, we will investigate the process of secondary succession. Learn about where secondary succession happens, why it happens, how it happens, and what it looks like.

What is Species Diversity? - Definition, Importance & Examples

8. What is Species Diversity? - Definition, Importance & Examples

Have you ever wondered how many species live on Earth? Earth is full of amazing creatures. In this lesson, you will learn about the importance of species diversity. At the end, test your knowledge with a quiz.
