About This Chapter
Trophic Levels & Biomass Energy - Chapter Summary
The lessons in this chapter provide an overview of trophic levels and biomass energy. In these lessons, you'll find a discussion of the energy flow through food chains, ecological communities, energy transfer in ecosystems, and much more. After completing the chapter, you should be prepared to:
- Define the food chain and provide examples of different food chains
- Explain biomass and the methods used to determine it
- Diagram the flow of metabolic energy using an energy pyramid
- Discuss biomass transfer between different trophic levels and the impact on species
These lessons are brief and engaging, which helps you to easily understand the information presented. Each lesson is accompanied by a brief multiple-choice quiz to test your knowledge. You can also use the more extensive chapter exam to test your understanding of chapter topics as a whole. If you have any questions, feel free to reach out to our instructors.
1. What is a Food Chain? - Examples, Overview
Energy is never created nor destroyed, but it can be passed from one organism to another. A food chain shows how this energy flow occurs. This lesson will define what a food chain represents, go through specific examples of food chains, and compare and contrast a food chain with a food web.
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.
3. What is an Energy Pyramid? - Definition & Examples
When organisms eat other organisms, energy is transferred. An energy pyramid can be used to diagram this flow of metabolic energy. Here we will examine the definition of an energy pyramid, look at some examples, and finish with a brief quiz.
4. Efficiency of Biomass Transfer Between Trophic Levels
Energy is transmitted through food chains within food webs. This lesson will go into detail regarding the efficiency of these energy transfers between the different levels of food chains and food webs.
