Ch 29: Praxis Biology: Ecosystem Ecology

About This Chapter

Use this chapter of video lessons to prepare for the Praxis Biology exam, especially the section that deals with ecosystem ecology. Topics include biodiversity, ecological cycles and habitats.

Praxis Biology: Ecosystem Ecology - Chapter Summary

This chapter is designed to build upon and refresh your college-level coursework in ecosystem ecology. In preparation for the Praxis Biology test, the instructor will discuss the following topics:

  • Coral reef, savanna and tropical rainforest biomes (habitats)
  • Coast line, taiga, temperate grassland and tundra biomes
  • The biological diversity found in freshwater, ocean rainforest and temperate rainforest ecosystems
  • The water cycle, including condensation, evaporation and precipitation
  • Biogeochemical cycling and the phosphorus cycle
  • Acid rain, fossil fuels and the nitrogen cycle
  • The carbon cycle, with an explanation of long-term carbon storage
  • The natural flow of matter between ecosystems, including human transport and migration

Objectives of the Praxis Biology Test: Ecosystem Ecology Course

The Praxis Biology test assesses a prospective teacher's readiness to teach biology at the secondary school level. Test content is similar to what you might have learned in your lower-level, college biology courses, and approximately 15% of the 150 multiple-choice questions are related to ecology. In terms of subject matter and presentation, the exam reflects the standards established by the National Science Teacher Association, as well as the National Science Education Standards.

Each tutorial in the Ecosystem Ecology chapter includes an online quiz, which can show you how well you retained the major points of the lesson. Similar to the questions found on the actual exam, the quiz gives you some idea of what to expect on test day.

Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More

1. Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More

Take a trip around the world and learn all about different biomes. Why can you only find certain plants and animals in specific places? What are the most fertile climates on Earth? Watch on to answer these and other questions.

Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines

2. Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines

Take a trip with us in this lesson, starting in the Pacific Ocean, traveling across California through the Central Valley and up to the peaks of the Sierra Nevada mountains. We'll learn how oceans, elevation, and people can determine which types of biomes are found in different areas and check out the Earth's most massive and oldest organisms.

Ecosystems of Oceans and Freshwater: Biological Diversity and Water

3. Ecosystems of Oceans and Freshwater: Biological Diversity and Water

In this lesson, you'll learn about the biodiversity of ecosystems based on water. You will discover that marine, freshwater and a mixture of salt and freshwater create very different ecosystems, which in turn influence the amount of biodiversity that is found in these habitats.

Biological Diversity and the Forest: Ecosystems of the Rainforests and Temperate Forests

4. 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.

Primary Productivity of Biomes

5. Primary Productivity of Biomes

Imagine a desert, a rainforest, and a lake. All of these areas are similar in that there are plants growing in them. These areas all vary because the amount of plant production is different based on the type of habitat. This lesson will explore the concept of primary productivity and how it varies by biomes. It will also discuss the most productive biomes and the biomes that produce the least biomass.

The Water Cycle: Precipitation, Condensation, and Evaporation

6. 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.

Biogeochemical Cycling and the Phosphorus Cycle

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.

The Nitrogen Cycle, Acid Rain and Fossil Fuels

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.

The Carbon Cycle and Long-Term Carbon Storage

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.
