1. Explain the distribution of abiotic and biotic factors in shallow and deep lakes.
2. Apply appropriate plankton research methods in the field and in the laboratory.
3. Explain the results of research or experiment to assess trophic/saprobic degree of aquatic ecosystems, seasonal dynamics of plankton and its role in food chains in aquatic ecosystems.
4. Process the results of abiotic and biotic interactions in the appropriate computer programs.
5. Suggest possible measures to reduce eutrophication in standing water.
