Worktime: Build a Web
Closing: Destroy a Web
HW: Quiz and final draft of your carbon atom story will be turned in on Friday.
Benchmark 7.3.1
Objective: Analyze the impact of carbon cycle changes on food web dynamics. You will be able to tell me what happens to a food web when certain bad situations arise.
First, check out this site to see how global warming happens. Now, read this article from the Honolulu Advertiser about global warming. The article says that the government wants to regulate greenhouse gases (such as carbon dioxide) because they are dangerous to humans. How are these gases dangerous to humans?
Now build a food web at this website. Imagine that most of the population of jaguars, the top predator, dies from a disease. What would happen to the rest of the organisms in the food web. Why would this happen?
Now watch this presentation to learn some more about global warming and about how a change in the population of one organism can affect all of the organisms in a community.
