D. The bird population will become extinct is not a possible effect the zebra mussels would have on the birds native to the Great Lakes. While the zebra mussels may have a significant impact on the ecosystem and the food chain, it is unlikely that they would cause the extinction of an entire bird population. However, the other statements are possible effects that the zebra mussels could have on the birds, such as changing their diet or causing them to move to new locations to find food.
