Ch 15: MTTC Integrated Science (Secondary): Ecological Systems

About This Chapter

Use these lessons to study for questions on the MTTC Integrated Science (Secondary) exam about ecological systems. Review biotic and abiotic factors of ecosystems, structures of ecosystems, populations of ecosystems and more.

MTTC Integrated Science (Secondary): Ecological Systems - Chapter Summary

This chapter has been put together to help you study for the Michigan Test for Teacher Certification (MTTC) Integrated Science (Secondary) exam and improve your understanding of the structures and processes of ecosystems. It includes a series of short, engaging videos about:

  • Levels of ecology and ecosystems
  • Biotic and abiotic factors
  • Studies of community ecology
  • Functions of habitats and ecological niches
  • Food chains and interspecific competition
  • Characteristics and behaviors of populations
  • Conservation biology
  • Ecological succession

These lesson videos are mobile device friendly so that you may watch them at any time or place. You can also read the text transcripts for an additional written overviews of the material. If at any time you develop a questions about these topics, be sure to send it to our instructors so that they can help you master the material before test day.

MTTC Integrated Science (Secondary): Ecological Systems Chapter Objectives

The MTTC Integrated Science (Secondary) exam is used to determine your eligibility for a Michigan secondary teacher endorsement in integrated science. On test day you will be asked to complete 100 multiple-choice questions, 25% of which will be about the life sciences. This section may include questions about ecosystems. Use these lessons to prepare and improve your understanding of the structures of ecosystems and the factors that affect them.

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.

What is Biotic? - Definition, Factors & Examples

2. 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

3. 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.

Community Ecology: Definition & Types

4. Community Ecology: Definition & Types

Community ecology looks at the interactions between populations of organisms. Here we explore a polar ecosystem in Greenland to describe what community ecology entails and what it really means to be at the top of the food chain.

Ecosystems, Habitats and Ecological Niches

5. Ecosystems, Habitats and Ecological Niches

Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

6. 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.

Interspecific Competition, Competitive Exclusion & Niche Differentiation

7. 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

8. 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

9. 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

10. 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.

Dispersal, Colonization, and Island Biogeography

11. 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

12. 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.

Ecological Succession: From Pioneer to Climax Communities

13. Ecological Succession: From Pioneer to Climax Communities

Just as people grow and change so, too, do ecosystems. Watch this lesson to learn about ecological succession from the beginning stages of development to a community's ultimate destination, or climax.

How Introduced and Invasive Species Alter Ecological Balance

14. How Introduced and Invasive Species Alter Ecological Balance

What happens to your block when a new neighbor moves in? Something changes, right? Now think about that on an ecological scale: what happens to an environment when a new SPECIES moves in?
