1. explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills

     Human activities that majorly impact the biochemical cycling are pollution through extraction of fossil fuels. The burning and use of these fuels also impacts the whole process of the cycling. Causing the processes to occur rapid disrupting the whole cycle. As far as Cultural eutrophication goes the pollution created by the use of fossil fuels and also the use of fertilizers are then put into our water system. The water then inevitably goes into our lakes and streams causing mass fish kills and water pollution.
