Ch 3: Habitats & Ecosystems

About This Chapter

Investigate these lessons to discover how habitats can affect ecosystems and vice versa. You can use this chapter to broaden your knowledge of environmental studies, and it can help you prepare for an exam or earn continuing education credits.

Habitats & Ecosystems - Chapter Summary

Scientists often study habitats and ecosystems separately, but in fact habitats are found within ecosystems, so the two significantly influence each other. These lessons address major factors that can affect both habitats and ecosystems, such as issues with population, environmentalist concerns, finding a balance, and more. Our instructors introduce you to these concepts by using real world or highly realistic examples. By using these examples, you gain a deeper understanding of each concept, and more often than not you will see the practical applications of these concepts. Since the chapter has been separated into short lessons, the instructors can keep your focus concentrated on the most pertinent facts, vocabulary terms, and diagrams. Should any of the information seem unclear, our instructors are ready to answer any of your questions. Topics addressed in this chapter include:

  • Ecosystems and carrying capacity
  • Dispersion and migration patterns
  • Habitat fragmentation and conservation biology
  • Concerns with metapopulations
  • Ecological balance and invasive species
