About This Chapter
Who's it for?
This unit of our AP Environmental Science Homeschool course will benefit any student who is trying to learn about different kinds of ecosystems. There is no faster or easier way to learn about environmental science. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about long-term carbon storage and the carbon cycle.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need an environmental science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and an Ecosystems unit exam confirm understanding or identify any topics that require review.
Ecosystems Unit Objectives:
- Learn about the laws of thermodynamics.
- Study food chains and energy flow in ecosystems.
- Define global ecology.
- Read about acid rain and the nitrogen cycle.
- Learn about biodiversity.
- Explore the phosphorous cycle and biogeochemical cycling.
1. The Environment, Levels of Ecology and Ecosystems
Do you know the difference between an environment and an ecosystem? In this lesson, you'll find out what makes an environment, and what makes an ecosystem. You'll also learn what ecology is and some of the ways that scientists study ecology using organisms, populations, communities, ecosystems and even the entire biosphere.
2. Ecosystems, Habitats and Ecological Niches
Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.
3. The Laws of Thermodynamics
Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.
4. Global Ecology: Definition and Overview
A large oil spill in the middle of the ocean and the release of greenhouse gases into the atmosphere are examples of environmental problems that can influence the entire planet. This lesson will explore the study of environmental problems occurring on a global scale, including the impact of globalization and current major global environmental problems.
5. What is Biodiversity? - Definition and Relation to Ecosystem Stability
Imagine making a list of all of the species you have ever heard of; it would be an enormous list! There are many different species on this planet. This lesson will explore the diversity of species, as well as the different types of diversity and how diversity of life is essential for maintaining healthy ecosystems.
6. 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.
7. Biogeochemical Cycling and the Phosphorus Cycle
In this video lesson, we'll take a look at how elements large and small use other elements to grow. This is achieved through cycles. We'll look at macronutrients, trace elements and the biogeochemical and phosphorous cycles.
8. The Nitrogen Cycle, Acid Rain and Fossil Fuels
Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.
9. 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.
10. Fossil Fuels, Greenhouse Gases, and Global Warming
In this video lesson, you'll learn what roles fossil fuels and greenhouse gases play in global warming, as well as what life on Earth can expect due to rising carbon dioxide levels within Earth's atmosphere.
