About This Chapter

Everything you need to remember about evolving ecosystems for the MTEL Middle School Math/Science exam is right here! Use our brief video lessons and quizzes for your study sessions so you can answer similar questions on your exam.

MTEL Middle School Math/Science: Evolving Ecosystems - Chapter Summary

Watch a 5-10 minute video lesson about the difference between a tropical rain forest and temperate grassland. In this chapter, you will able to use our short quizzes to test your memory of natural selection. By the end, you will be able to recall the information needed to answer exam questions about the following:

  • Types and characteristics of biomes like the desert, tundra and more
  • Primary productivity
  • Natural selection
  • Evolution
  • Biotic potential and population
  • Definition of abiotic factors, environmental sustainability, and conservation biology
  • Types of environmental health
  • Environmental health threats
  • Definition and impact of an invasive species
  • Humans' influences on ecosystems

If you need to study on the go, you can print out a worksheet along with the answers. Reviewing is a simple task with this chapter, because you can view the parts of the videos that pertain to the correct answers of your quizzes. The timeline located under each video lesson exists to give you the ability to jump back and forth between different topics in the video. Contact our instructors or experts if you have any questions.

MTEL Middle School Math/Science: Evolving Ecosystems Objectives

The Massachusetts Tests for Educator Licensure test is taken by anyone who wishes to obtain their teaching license. The material for the lessons and quizzes in this chapter link to the Biology section of the MTEL Math/Science exam. The exam's Biology section stands for 8% of it. You will be asked to show your understanding of evolution among living things and facts about populations and ecosystems. Your test will be taken on a computer and will contain 100 multiple-choice questions and 2 open-ended questions.

Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More

1. Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More

Take a trip around the world and learn all about different biomes. Why can you only find certain plants and animals in specific places? What are the most fertile climates on Earth? Watch on to answer these and other questions.

Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines

2. Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines

Take a trip with us in this lesson, starting in the Pacific Ocean, traveling across California through the Central Valley and up to the peaks of the Sierra Nevada mountains. We'll learn how oceans, elevation, and people can determine which types of biomes are found in different areas and check out the Earth's most massive and oldest organisms.

Primary Productivity of Biomes

3. Primary Productivity of Biomes

Imagine a desert, a rainforest, and a lake. All of these areas are similar in that there are plants growing in them. These areas all vary because the amount of plant production is different based on the type of habitat. This lesson will explore the concept of primary productivity and how it varies by biomes. It will also discuss the most productive biomes and the biomes that produce the least biomass.

Natural Selection & Adaptation: Definition, Theory & Examples

4. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Theories of Evolution: Lamarck vs. Darwin

5. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

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.

Abiotic Factors of an Ecosystem: Definition & Examples

7. 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 Environmental Health? Definition, Types & Sources

8. What Is Environmental Health? Definition, Types & Sources

In this video lesson, you will learn about environmental health. You will also learn about threats to environmental health and how to distinguish between different categories of environmental hazards.

Environmental Sustainability: Definition and Application

9. Environmental Sustainability: Definition and Application

Environmental sustainability allows for the needs of man to be met without jeopardizing the ability of future generations to meet their needs. Learn applications of environmental sustainability, including sustainable agriculture, forestry and energy.

Understanding & Assessing Threats to Environmental Health

10. Understanding & Assessing Threats to Environmental Health

In this lesson you will learn how threats to environmental health are assessed. You will also learn how management decisions are made based on such threats and their risks.

What Is an Invasive Species? - Definition, List & Effects

11. What Is an Invasive Species? - Definition, List & Effects

This lesson focuses on a group of organisms called invasive species. You'll learn what makes a species invasive and see some examples of invasive species. You'll also discover why invasive species are considered a problem and explore the impacts they have on the environment, the economy and on humans.

Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

12. Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

In this lesson, you'll learn how humans overexploit or overharvest species. You will discover the primary way in which humans are responsible for overfishing. You will also learn about how this negatively impacts ecosystems.

What Is Conservation Biology? - Definition & Principles

13. What Is Conservation Biology? - Definition & Principles

Conservation biology aims to reduce the human impact on the environment by looking for the causes and possible solutions to these problems. In this lesson, you'll learn about conservation biology and the different types of conservation.
