Ch 7: ScienceFusion Ecology & the Environment Unit 2.3: Energy & Matter in Ecosystems

About This Chapter

The Energy & Matter in Ecosystems chapter of this ScienceFusion Ecology & the Environment Companion Course helps students learn the essential lessons associated with energy and matter in ecosystems. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Energy & Matter in Ecosystems textbook chapter.

How It Works:

  • Identify the lessons in the ScienceFusion Energy & Matter in Ecosystems chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the energy and matter in ecosystems 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:

  • Chemical and physical properties of matter
  • Definition of energy
  • Ecology producers and consumers
  • First law of thermodynamics
  • Law of conservation of mass
  • Energy pyramids
  • Matter and energy transfers and transformations
  • The water cycle
  • Definitions for the carbon and nitrogen cycles

Matter: Physical and Chemical Properties

1. Matter: Physical and Chemical Properties

How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.

What is Energy? - Definition and Significance in Nature

2. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Ecology Producer: Definition & Explanation

3. Ecology Producer: Definition & Explanation

This lesson will define what a producer is and what its role is in an ecosystem. It will also discuss the different kinds of producers and give some specific examples of them.

Ecology Consumer: Definition & Explanation

4. Ecology Consumer: Definition & Explanation

This lesson will discuss the role of consumers in an ecosystem. It will describe their place in a food chain and how they interact with other organisms. Specific types of consumers will be presented.

First Law of Thermodynamics: Law of Conservation of Energy

5. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

The Law of Conservation of Mass: Definition, Equation & Examples

6. The Law of Conservation of Mass: Definition, Equation & Examples

Read about the law of conservation of mass, its role in chemistry, and its importance in the universe. Learn the equation, review examples, and test your knowledge of the material with a short quiz.

What is an Energy Pyramid? - Definition & Examples

7. 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.

The Water Cycle: Precipitation, Condensation, and Evaporation

8. 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.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

9. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
