▶ Your Answer : The lecturer argues that it is unclear that zebra mussels offered serious threat. This contradicts the reading passage's claim that there are reasons to believe that this encroachment cannot be stopped and that it poses a serious threat to freshwater fish populations in all of North America.
First of all, the speaker argues that in the past, people did not have knowledge. The speaker explains that ship has ocean water, so zebra mussel would have been dead because of ocean water. This refutes that the history of the zebra mussel's spread suggests that the invasion might be unstoppable. It is a prime example of an invasion made possible by human transportation. In addition, according to the speaker, the period that they can dominate new habitat is just begging period. The speaker maintains that local birds exchanged their diet habit and ate zebra mussel. This refute the reading passage's assertion that once zebra mussels are carried to a new habitat, they can dominate it and they often have no predators in their new habitats. The final point made by the lecturer is that they gave both negative effect and positive effect to native. The speaker says that they ate plankton and other plankton eaters dead and bottom's fish species ate them. This rebuffs the reading passage's argument that zebra mussels are likely to cause a decline in the overall fish population in habitats where they become dominant.
