Invasive Species and Ecology Review

Today students reviewed some ideas in ecology with the following questions.

Four check-in questions:
1. Compare and contrast a food web to a food chain.  Which is more realistic?  Why?

2. How does a modeling program like Ecobeaker help us in science?  What are its limitations (What can't it provide for us)?

3. List three different trophic levels found in an ecosystem.  Give a specific organism that can be linked to each of the levels and what it feeds on (how does it get its energy?).

4. How does the energy in a food chain transfer from one trophic level to another?  How much energy actually passes from one organism to another organism?




We also started to discuss the America's Most Unwanted Project.
Here you will find resources, graphic organizers, and the rubric.

Monday October 21st - Invasive Species

Here are the links for today's discussion on invasive species.
Specifically we will be looking and reading about Northern Pike.

and
Bangor Daily News

Two questions to consider:
1. How did the pike get to Maine and where do they populate?
2. How are people combatting the infestation of pike?
