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. Ecological Succession: From Pioneer to Climax Communities
Just as people grow and change so, too, do ecosystems. Watch this lesson to learn about ecological succession from the beginning stages of development to a community's ultimate destination, or climax.
3. What Are Fossil Fuels? - Definition, Advantages & Disadvantages
Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable. Learn more about these fuels, including the pros and cons of using them.
4. Renewable & Non-Renewable Resources: Definition & Differences
We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
5. Geothermal Energy: Advantages and Disadvantages
Geothermal energy is heat energy that is stored within the earth. Learn the methods being used to tap into this thermal energy to heat buildings and generate electricity as well as the advantages and disadvantages of this renewable energy source.
6. Hydroelectric Energy: Definition, Uses, Advantages & Disadvantages
In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks of using this type of renewable resource for energy production.
7. Voltage Sources: Energy Conversion and Examples
We use them every day, but no one really gives them much thought. What are we talking about? Why, voltage sources, of course! Batteries and generators are two of the most common sources of voltage that power our daily lives. We'll look at them in detail to see how they work.
8. Pollution: Physical, Chemical & Biological
Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.
9. What Is Eutrophication? - Definition, Causes & Effects
Ever heard the phrase, 'too much of a good thing?' Eutrophication is a good example of this. When aquatic systems have an overabundance of nutrients, the entire system suffers and can ultimately become unlivable.
10. The 3 Rs of Reducing Solid Waste: Reuse, Reduce & Recycle
Reduce, reuse, recycle! In this lesson, we will explore the three Rs of reducing solid waste. We will also investigate examples of each of the three Rs, and how people can do their part to help reduce solid waste.
