2 Ballast Water Video Watch the video on ballast water in order to explain: 1.What is ballast water? 2.Why do ships use ballast water? 3.What can be harmful about ballast water? 4.Name at least 2 organisms that have come from ballast water. 5.How have they caused problems in marine ecosystems? 6.How many species have been found in the Great Lakes that have likely come from ballast water?

3 Zebra Mussells

4 Water Comb Jelly

5 Independent Research For the invasive species provided please explain: What trophic levels have been effected by the introduction of this species? How did this species get introduced to the area?
