Ecosystems in Action: Population & Community Dynamics

Students will know what lives in the Hudson River, and will be able to create a food web drawing to represent the organisms living in the river. They will also know that the Hudson River food web is changing in response to the zebra mussel invasion, and will be able to make predictions about how native organisms will be affected by this invasion.  

Students will know how the zebra mussel invasion affected the food web of the Hudson River and be able to explain at least two connections within the food web that were affected using evidence from provided graphs.

Students will know how the zebra mussel has changed the Hudson River ecosystem and be able to explain how a biotic change affects the abiotic conditions in the Hudson River.

Students will know how the zebra mussel invasion has changed the Hudson River and be able to use graphed data to explain the history of these changes.
