The zebra mussel is a shellfish native to Europe. During the early 1900's, it was accidentally brought to the United States in the ballast of a ship traveling to the Great Lakes. It has no predators in the Great Lakes. What impact are zebra mussels likely to have on food chains in the Great lakes?
since they have no predators the zebra mussel population will grow rapidly. Whatever the zebra mussels consume will have a major decrease in population since there are so many zebra mussels.
