About This Chapter
Biochemical Cycles - Chapter Summary
If you need a review of biochemical cycles, look no further than this chapter's video lessons. Our instructors break down the concept of biogeochemical cycling and guide you through some of the important cycles involving the elements nitrogen, carbon and phosphorus. You'll also examine each component of the water cycle from precipitation to evaporation. Once you've finished viewing the lessons, you should be able to:
- List and describe the parts of the water cycle
- Define biogeochemical cycling
- Explain the phosphorus cycle
- Describe the nitrogen cycle and acid rain development
- Understand the carbon cycle
Our video lessons are typically less than 10 minutes long and are full of diagrams and other graphics to help you learn about biochemical cycles in a simplified way. Video tags allow you to go back and rewatch important concepts as needed. After you've studied the lessons, you can take our self-assessment quizzes to see how well you understand this science material.
1. The Water Cycle: Precipitation, Condensation, and Evaporation
This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.
2. 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.
3. 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.
4. 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.
