Ch 38: MTEL Biology: Ecology

About This Chapter

Let us help you review everything that is known about ecology, in preparation for the MTEL Biology exam. Our video lessons and self-assessment quizzes afford you several related approaches that can help you correctly answer these types of questions on the test.

MTEL Biology: Ecology - Chapter Summary

You can use the lessons in this chapter to aid your recollection of ecology to prepare for the MTEL Biology exam. The videos cover all the topics you need to know, including:

  • Environment, ecology and the ecosystem
  • Food chains
  • Predator/prey interactions
  • Symbiotic relationships
  • Carrying capacity, migration and dispersion
  • Dispersal and colonization
  • Conservation biology
  • Social behavior

Our knowledgeable instructors highlight the important dimensions of ecology. You can view the lessons as videos or transcripts, and if you have any questions you may submit them to our experts for assistance. After you finish each lesson, be sure to take the self-assessment quizzes to ensure you grasped the information fully. By using our multiple approaches, refreshing your knowledge of ecology is easy to do and fun.

Objectives of the MTEL Biology: Ecology Chapter

The MTEL Biology exam evaluates your knowledge and understanding of all aspects of the field of biology. The topics in the Ecology chapter are part of the Populations, Ecosystems and the Environment Objectives of the exam which includes 16-18 multiple-choice questions. By taking the self-assessment quizzes that come with each lesson, you'll be able to check on your comprehension and get some idea of the kinds of questions you will see on the test.

The MTEL Biology exam includes multiple-choice and open-response questions. With the multiple choice questions, you will read a passage or question and then select the correct response from several presented to you. With the open-response questions, you will demonstrate your integration of biology information by writing organized, articulate and logical essays on biology topics.

The Environment, Levels of Ecology and Ecosystems

1. The Environment, Levels of Ecology and Ecosystems

Do you know the difference between an environment and an ecosystem? In this lesson, you'll find out what makes an environment, and what makes an ecosystem. You'll also learn what ecology is and some of the ways that scientists study ecology using organisms, populations, communities, ecosystems and even the entire biosphere.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

2. Food Chains, Trophic Levels and Energy Flow in an Ecosystem

In this lesson, you'll learn about food chains, food webs, and the different roles that organisms play in an ecosystem. You'll also learn about how energy flows through an ecosystem.

Biogeochemical Cycling and the Phosphorus Cycle

3. Biogeochemical Cycling and the Phosphorus Cycle

In this video lesson, we'll take a look at how elements large and small use other elements to grow. This is achieved through cycles. We'll look at macronutrients, trace elements and the biogeochemical and phosphorous cycles.

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.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

5. Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

You probably know that skunks can be quite stinky, bees sting and monarch butterflies are pretty, but do you know why? This lesson will introduce you to the reasons why some animals look or act the way they do and how these things relate to the predator/prey relationship.

Symbiotic Relationships: Mutualism, Commensalism & Parasitism

6. Symbiotic Relationships: Mutualism, Commensalism & Parasitism

If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how these relationships can have a positive, negative, or neutral effect on the individual species.

Populations: Density, Survivorship and Life Histories

7. 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.

Carrying Capacity, Migration & Dispersion

8. 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.

Dispersal, Colonization, and Island Biogeography

9. 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.

Conservation Biology, Habitat Fragmentation, and Metapopulations

10. Conservation Biology, Habitat Fragmentation, and Metapopulations

It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.

Social Behavior: The Cost-Benefit of Altruism and Kin Selection

11. Social Behavior: The Cost-Benefit of Altruism and Kin Selection

Ever wonder why people are more likely to help their relatives than complete strangers? Social behavior can help explain this and other actions. Let's look at the cost of certain behaviors.
