Discover more about ecosystems and the effects of pollution through the lessons provided to you in this chapter. You can even learn about food chains and different resources such as fossil fuels. All of the lessons are mobile friendly, so you can access them in the comfort of your home or on-the-go with your mobile device. By the time you finish watching or reading these lessons, you should know about:
- Different ecosystems and habitats
- The field of global ecology
- Relationship between biodiversity and the stability of the ecosystem
- Food chains and energy flow
- The nitrogen cycle
- Fossil fuels
- Impact of greenhouse gases and global warming
- Examples of decomposers
1. 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.
2. 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.
3. 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.
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. 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.
6. 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.
7. 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.
