Energy Cycling in the Biosphere
Questions from the Energy Pyramid Reading:
|
We will be reviewing food webs and how energy is transferred from one individual to another in the food chain. Eventually we will expand upon this topic to learn about the 10% rule and how our meat-rich diets may be extremely inefficient! I have provided you with extra readings "15.6-15.8 Energy and chemicals flow within ecosystems" and the National Geographic reading about eating insects.

Cats In Borneo Reflection Questions:
- How does the story of Borneo exemplify the idea of ecosystems and the interaction of organisms (specifically the importance of all organisms in that ecosystem)?
- How does the story exemplify how humans (in our attempt to fix one thing), cause unforeseeable problems in ecosystems?
- Explain how a toxin in a food web will harm some while killing others- why did the mosquitos and cats die while other things lived? (hint: research bioaccumulation & biomagnification)
- Explain why you think DDT has been banned in the U.S. but is still in production and used in countries all over the world.
- If DDT is still being used around the world, but not in the U.S.- are we still exposed to it?
- Do you think scientists should have sprayed the island with DDT? If not, what should they have done about the Malaria issue?
