Ch 75: MTEL Middle School Math/Science: Ecosystems

About This Chapter

The lessons in this chapter emphasize ecosystems, animal habitats and environmental challenges. Revisit these topics as you get ready to take the MTEL Middle School Math/Science exam.

MTEL Middle School Math/Science: Ecosystems - Chapter Summary

Expand your knowledge of our planet's ecosystems and habitats when you review the information in this chapter. For example, as you look at this chapter's online video lessons, you can explore biogeochemical cycles and global environmental concerns as well as the importance of food chains and diverse life forms within ecosystems. When it's time to take the MTEL Middle School Math/Science examination and address questions on ecosystems, you can be prepared. After studying, you might be able to answer questions related to:

  • Noting the differences between ecosystems and the environment
  • Identifying the locations of various ecosystems
  • Understanding more about global and ecosystem ecology
  • Defining biodiversity and examining the phosphorus and carbon cycles
  • Explaining the role of a food chain in an ecosystem
  • Discussing the outcomes of inter-specific competition and the implications of predator / prey interactions

Study these online lessons during your spare moments with the help of an Internet-connected device. Each of the interactive lessons is short, but filled with facts about ecosystems. Learn from experienced instructors who make the process fun. Quizzes, worksheets transcripts, navigational video tags and an ask-an-expert area are just some of the convenient features and functions you'll find in this chapter.

MTEL Middle School Math/Science: Ecosystems Chapter Objectives

Biology is the ninth subarea of the MTEL Middle School Math/Science examination. This portion of the assessment will evaluate your knowledge of ecosystems. It covers many of this chapter's topics, including food chains, food relationships and the relationships between organisms. The subarea accounts for 8% of the examination, and it includes 9-11 multiple-choice questions. This four-hour assessment is administered by computer and includes a total of 100 multiple-choice questions and two open-response assignments.

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.

Ecosystems, Habitats and Ecological Niches

2. 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.

Ecosystem Ecology: Definition & Explanation

3. Ecosystem Ecology: Definition & Explanation

What powers life? How much energy do animals get from eating plants? What short- and long-term effects will climate change have on our environment? Asking questions such as these help ecologists better understand ecosystems and the processes within them.

Global Ecology: Definition and Overview

4. Global Ecology: Definition and Overview

A large oil spill in the middle of the ocean and the release of greenhouse gases into the atmosphere are examples of environmental problems that can influence the entire planet. This lesson will explore the study of environmental problems occurring on a global scale, including the impact of globalization and current major global environmental problems.

What is Biodiversity? - Definition and Relation to Ecosystem Stability

5. What is Biodiversity? - Definition and Relation to Ecosystem Stability

Imagine making a list of all of the species you have ever heard of; it would be an enormous list! There are many different species on this planet. This lesson will explore the diversity of species, as well as the different types of diversity and how diversity of life is essential for maintaining healthy ecosystems.

Biogeochemical Cycling and the Phosphorus Cycle

6. 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.

The Carbon Cycle and Long-Term Carbon Storage

7. The Carbon Cycle and Long-Term Carbon Storage

All living organisms have a role in the carbon cycle. Do you know you understand how humans, animals and plants use carbon? This lesson will introduce you to the carbon cycle and explain how it functions on a global scale.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

8. 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

9. 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

10. 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.
