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.

Lions Video What types of animal relationships were in this video? What are some examples of predators and prey? What adaptations did the lions use to be successful predators?

Vocabulary: Add these terms to your Chesapeake Bay Vocabulary Charts and define them using your what you already know. Predator- Prey- Mimicry- Parasite- Host- Producer- Consumer- Herbivore- Carnivore- Decomposer-

Predator- An organism who feeds on other organisms. Prey- An organism who is fed on by other organisms. Mimicry- Pretending to be another organisms or object as a means of survival. Parasite- Organism who use other organisms as a means of survival – usually without the intent on killing them. Host- Organism infected by a parasite.

Producer- Autotrophs; organisms who synthesize their own food. Consumer- Heterotrophs; organisms who feed on other organisms for food. Herbivore- Organisms who eat vegatation only. Carnivore- Organisms who feed on animals. Decomposer- Organisms who break down dead and decaying matter as a food source.

What do you already know? 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.
