About This Chapter
Biotic & Abiotic Factors - Chapter Summary
In this chapter on biotic and abiotic factors, our mobile-friendly platform helps you review the various factors that come into play in ecosystems. Additionally, you will take a look at how people use decomposers. Upon completion of the chapter, you should be able to:
- List the components of an ecosystem
- Define biotic factor and related terminology
- Provide examples of abiotic factors of an ecosystem
- Explain how energy flows through an ecosystem
- Recall the role decomposers play in the environment
- Discuss the types of forests found on the earth
Our subject-matter experts present these topics in a way that is easy to understand. If you find yourself struggling with a topic, you can use the Help feature to submit questions to the instructors. A short quiz is available to test your understanding of each lesson, and the quizzes can also be printed for offline study.
1. What Is an Ecosystem? - Definition & Explanation
Similar to a car engine that is made up of multiple parts working together, an ecosystem has interacting parts that support a whole. But how do we define an ecosystem and what are the components they consist of?
2. Biotic Factor: Definition & Examples
This lesson focuses on the meaning of the term 'biotic factor.' It also introduces other terminology such as the words 'abiotic' and 'ecosystem'. There are real-world examples embedded in the lesson, and a brief quiz follows.
3. Abiotic Factors of an Ecosystem: Definition & Examples
When it comes to ecosystems, a mountain, a river, and a cloud have more in common than you might think. Abiotic factors have specific and important roles in nature because they help shape and define ecosystems.
4. 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.
5. What is a Decomposer? - Definition & Examples
Decomposers are an often overlooked part of the natural world, but their job is an important one. Learn what decomposers are, what role they have in the environment and how people use them.
6. Biological Diversity and the Forest: Ecosystems of the Rainforests and Temperate Forests
In this lesson, you'll learn about three main types of forests found on earth: coniferous, deciduous and tropical rainforests. You'll also discover how the ecosystems where these trees are located affect the biodiversity within them.
