have a wetland that has issues with eutrophication and is choked
with algae (phytoplankton). You do an inventory of the species in
your wetland and find, in addition to algae, there are many species
of zooplankton, several species of filter feeding fish that consume
phytoplankton, and two species of fish that eat zooplankton. Under
what circumstances would adding piscivorous fish increase the water
quality of your wetland? Diagram the trophic cascade in your lake
with and without piscavores. Using the concept of a trophic
cascade, describe (or draw) the conditions where control of algae
would be successful and where control of algae would fail.
