Learning Outcomes

Upon successful completion of the course, the student will be able to:

  • Define the concept of the system and the use of models in environmental engineering.
  • Recognize the ecosystem as a system.
  • Describe the basic concepts and operating principles of various ecosystems.
  • Recognize the main models, which define the operation and stability of an ecosystem.
  • Solve exercises based on those models.
  • Evaluate the meaning and the importance of the limiting factor in ecosystems.
  • Recognize the most important processes regarding the production and storage of energy.
  • Assess the main environmental factors that contribute to and affect the ecosystem stability.
  • Recognize the key environmental problems, regarding the deterioration and 
  • degradation of an ecosystem.
  • Record and assess events of environmental pollution.
