Answer:
During its parasitic phase, one sea lamprey can destroy an average of 18 kilograms of fish. As few as one in seven fish may survive a sea lamprey attack. Attacks have resulted in reduced stocks of lake trout, salmon, whitefish, cisco and burbot in the Great Lakes.

Answer:
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
