  • Of dominant anthropogenic types of pollution affecting freshwater ecosystems.


  • Shall be able to differentiate between major types of streams, rivers and lakes.
  • Shall be able to understand the exchange of matter between aquatic and terrestrial environments.
  • Shall be able to explain lake and river ecosystem dependence on light, temperature, nutrients and organic matter.
  • Shall be able to understand primary production, respiration and re-oxidation in freshwater ecosystems.
  • Shall be able to determine the significance of hydraulic conditions on chemical and biological dynamics in lakes and rivers.
