CEOE Middle Level Science: Ecosystems and Biomes - Chapter Summary

If your goal is to pass the CEOE Middle Level Science exam, you can improve your odds by going through this chapter's video lessons on ecosystems and biomes. Once you've studied each lesson, you could know more about:

  • The contrasts between ecosystems and environments
  • The parts and niches of ecosystems
  • Types of biomes, including desert, rain forest and grassland
  • Plants, animals and climate of the open ocean biome
  • The definition of primary productivity
  • Food chains within ecosystems

Knowledgeable instructors narrate the lessons and take the time to answer your topical questions as you submit them interactively. The lessons are short and entertaining. They can be studied anywhere or anytime when you access them via your smartphone, laptop, tablet or other device.

CEOE Middle Level Science: Ecosystems and Biomes Chapter Objectives

With 80 multiple-choice questions and one open-response question, the CEOE Middle Level Science exam will determine your qualifications to teach the subject to your own students.

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.

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

3. 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

4. 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.

Open Ocean Biome: Plants, Animals, Climate & Definition

5. Open Ocean Biome: Plants, Animals, Climate & Definition

Seventy-one percent of the surface of our planet is covered by the oceans. It should be no surprise that the open ocean biome is the largest biome on Earth. In this lesson, we will investigate the properties and inhabitants of the open ocean biome.

Primary Productivity of Biomes

6. 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.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

7. 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.
