Invasive species can be a big problem economically and environmentally. This simple food chain illustrates some of the feeding relationships in a (hypothetical) coastal area of Florida that has been heavily impacted by invasive green algae. One of your colleagues has the idea that introducing a new top predator (a big fish from China that will eat little fish) into the area could help to control the invasive green algae. His idea is that the new big fish will eat the small fish, resulting in fewer small crustaceans being eaten, so that there will be more of the crustaceans to eat the invasive algae. Explain the potential problems of your colleagues' plan, including at least two supporting details.
