Ch 3: Ecosystem Cycles & Processes

About This Chapter

Further develop your understanding of ecosystem cycles and processes with this overview that includes discussion of trophic levels, long-term carbon storage, the water cycle, and more. These concise lessons are a handy resource for individuals preparing for an exam or catching up on missed class time.

Ecosystem Cycles & Processes - Chapter Summary

This chapter includes lessons on ecosystem cycles and processes. Our expert instructors help you go over biomass, food chains, and evaporation. You'll also gain an understanding of how nitrogen is used. After completing the chapter, you should feel confident and ready to:

  • Explain how energy flows through an ecosystem
  • Discuss how ecologists quantify matter in an ecological community
  • Describe how the carbon cycle functions globally
  • List properties of nitrogen
  • Define condensation and precipitation
  • Differentiate between primary and secondary succession

Each lesson is accompanied by a brief multiple-choice quiz to assess how much of the content and details you can recall. Video timelines let you review only the topics you need to study. You can make the most of the chapter by printing the quiz in worksheet form to use as an offline study guide.

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.

What Is Biomass? - Definition & Explanation

2. What Is Biomass? - Definition & Explanation

In this lesson, you'll learn what ecologists use to quantify the amount of matter in an ecological community. This often relates to the amount of energy being produced by various parts of that community.

The Carbon Cycle and Long-Term Carbon Storage

3. 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.

What is Nitrogen? - Cycle & Formula

4. What is Nitrogen? - Cycle & Formula

Nitrogen is a vital element for all living things. This lesson walks through some of the properties of nitrogen, the nitrogen cycle, and other uses of nitrogen.

The Water Cycle: Precipitation, Condensation, and Evaporation

5. 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 Differences Between Primary & Secondary Succession

6. The Differences Between Primary & Secondary Succession

In this lesson you will learn about the differences between primary and secondary succession. You will also discover how and why each process occurs as well as their importance to the survival of a habitat.
