Ch 10: Energy Transformations in Living Things

About This Chapter

Through this chapter, with the assistance of our resources, we can help you review what you need to know about energy transformations in living things. Use our engaging video lessons and short quizzes to prepare for questions on autotrophs, heterotrophs and types of respiration.

Energy Transformations in Living Things- Chapter Summary

These lessons detail information about how energy is transferred from one living thing to another. The video lessons contain topics such as heterotrophs and aerobic cellular respiration. You'll examine how carbon fixation works in photosynthesis and learn about alternative methods of this process. All in all, in this chapter, you should:

  • Learn about the different types of autotrophs
  • Give examples of different types of heterotrophs
  • Summarize what occurs with carbon fixation in photosynthesis
  • Identify different methods of carbon fixation in plants
  • Explain the steps involved in aerobic cellular respiration
  • Know the definition of anaerobic respiration

Because our lessons are available online, via computer or mobile device, this chapter's numerous resources adapt to your schedule. The lessons are short but engaging, broken down in short tidbits that give you a better chance of retaining the material. You will have the chance to test your knowledge of the lesson information with the help of the quizzes that accompany each lesson.

Autotrophs: Definition, Examples & Types

1. Autotrophs: Definition, Examples & Types

As human beings, we need to eat living things for energy. Other organisms are able to make their own food. Autotrophs can provide energy sources for themselves as well as for those of us who can't produce it on our own.

Heterotrophs: Definition & Examples

2. Heterotrophs: Definition & Examples

In this lesson, you will learn about organisms that are not able to provide their own food and must eat other organisms to survive. Heterotrophs must consume other living material, which provides the energy they need to live.

Carbon Fixation in Photosynthesis: Definition & Reactions

3. Carbon Fixation in Photosynthesis: Definition & Reactions

In this lesson, you will discover what carbon fixation means, when it occurs and what enzyme is involved. The lesson will discuss where the process of carbon fixation falls in photosynthesis as well as give a brief idea of a process by which carbon can be freed from fixation.

Alternative Methods of Carbon Fixation in Plants

4. Alternative Methods of Carbon Fixation in Plants

What happens to plants when it gets too hot or dry for the normal cycles of creating energy to keep functioning? In this lesson, we are going to check out a couple alternative solutions adapted by plants to maintain energy production when the need arises.

Aerobic Cellular Respiration: Stages, Equation & Products

5. Aerobic Cellular Respiration: Stages, Equation & Products

Aerobic cellular respiration is the process in which our cells break down food and turn it into energy that cells need to perform their life functions. This lesson goes through the process, formula, and end results of aerobic cellular respiration.

Anaerobic Respiration: Definition, Equation & Examples

6. Anaerobic Respiration: Definition, Equation & Examples

Many organisms are capable of undergoing anaerobic respiration. In some cases, it's a 'backup plan' when oxygen is absent, and in other cases, they thrive that way. Here we will investigate what anaerobic respiration is, the equation and examples of it at work.
