Notes

An ecologic model based on fundamental principles of biology, chemistry and physics has been described. Basic ecologic processes including photosythesis, respiration, zooplankton grazing, fish predation, sedimentation, nutrient recycling, and others were shown to be capable of representation by mathematical functions. These functions can be assembled and operated together to simulate simultaneously physical, chemical and biological behavior of an ecosystem. Preliminary tests of the ecologic model indicate the reasonableness of the technique. It is concluded that model development and application will aid greatly in development of a more fundamental understanding of eutrophication processes and their control.
