Identifying Environmental Hazards

In this lab, you will determine how an invasive species-the zebra and quagga mussel-affects other species in the freshwater lake.

Instructions: You will write a 1-page lab report using the scientific method to answer the following questions:
· 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?
