The Effects of Zebra and Quagga Mussels Introduced into a Freshwater Lake

In this lab, you will determine how an invasive species—the zebra and quagga mussel—affects other species in the freshwater lake. Use the animation to help you come up with an answer to the following:

Why do you see increases and decreases in the invasive species population?
What are the implications associated with these alterations to the ecosystem as a whole?
