Lesson 6– Description:

Organisms of the Bay and their niche:Researching a selected type of the Chesapeake Bay aquatic ecosystem, students develop a food web of organisms and must label interactions and trophic levels.

Unit Goals:Identify the living organisms of the Bay.

Lesson Objectives:Research and explain organisms’ niche in the Bay ecosystem using food webs.Design an aquatic ecosystem food web.Explain the importance of microbes and vegetation of the Bay.

What examples of organisms do you know of that are examples of these terms?

Reaching the Chesapeake Bay’s Ecosystems

Today and tomorrow you will be researching ecosystems to find examples of organisms that live in specific ecosystems of the Chesapeake Bay watershed.

Using these organisms, you will be responsible for designing food webs to show the interactions of organisms of these places.

This is due at the end of class tomorrow.

Finish researching ecosystems to find examples of organisms that live in specific ecosystems of the Chesapeake Bay watershed and designing food webs to show the interactions of organisms of these places.

This is due at the end of class.
