Ch 55: Campbell Biology Chapter 55: Ecosystems and Restoration Ecology

About This Chapter

The Ecosystems and Restoration Ecology chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with ecosystems and restoration ecology. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Ecosystems and Restoration Ecology textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Ecosystems and Restoration Ecology chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the ecosystem and restoration ecology topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Definitions for food chains and trophic levels
  • Energy flow in ecosystems
  • Levels of primary productivity in biomes
  • Limitations on primary production in aquatic ecosystems
  • The definition for secondary production in ecosystems
  • What trophic efficiency and ecological pyramids are
  • The process of biogeochemical cycling
  • Parts of the water cycle
  • Nitrogen cycle processes
  • Parts of the carbon cycle
  • The function of bioremediation

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

1. 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.

Primary Productivity of Biomes

2. 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.

Primary Production in Aquatic Ecosystems: Light & Nutrient Limitations

3. Primary Production in Aquatic Ecosystems: Light & Nutrient Limitations

Production requires sunlight and nutrients, whether its on land or in the water. In this lesson, we look at how producers in aquatic ecosystems acquire both sunlight and nutrients in order to allow life to exist in water.

Secondary Production & Production Efficiency in Ecosystems: Definition & Example

4. Secondary Production & Production Efficiency in Ecosystems: Definition & Example

Every ecosystem is full of energy, and how this energy is transferred is important. In this lesson, we are going to explore the efficiency of energy production and transfer within an ecosystem and discover how this changes throughout the food chain.

Trophic Efficiency & Ecological Pyramids: Definition & Examples

5. Trophic Efficiency & Ecological Pyramids: Definition & Examples

If we're talking energy, being at the top of the food chain is not the place to be. In this lesson, we'll discuss how energy moves through the different levels of a food chain, and where you can get the most bang for your buck.

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 Water Cycle: Precipitation, Condensation, and Evaporation

7. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

The Nitrogen Cycle, Acid Rain and Fossil Fuels

8. The Nitrogen Cycle, Acid Rain and Fossil Fuels

Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.

The Carbon Cycle and Long-Term Carbon Storage

9. 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.

Bioremediation: Microbes Cleaning Up the Environment

10. Bioremediation: Microbes Cleaning Up the Environment

Bioremediation uses living organisms to clean up pollution. In this lesson, we will examine the role of microbes in bioremediation and why it is not a perfect solution for degrading environmental pollutants.
