4. 5.1 Vanishing Species Biodiversity: the diversity of plant and animal life in a particular habitat (or in the world as a whole); "a high level of biodiversity is desirable" How many different types do you have?

5. Biodiversity Makes an ecosystem more resistant to change or more able to survive a change in conditions. Not all species may survive, but some should. If a niche goes away, so do all the organisms that used it. Diversity makes an ecosystem more stable Edge Effect (Ecotone)

6. Human Benefits of biodiversity Beauty Drugs Ecological stabilty No plants, no oxygen No ocean, no moderated temperature on Earth

7. Threats to Biodiversity Habitat loss Habitat fragmentation Habitat degradation

8. Ozone layer Global warming-does it occur? Acid precipitation Water pollution Land pollution Groundwater pollution Land use Exotic pets

9. Global Warming On Nicenet a question is posted: The first question is "Does Global Warming Exist? You must research the topic and give your opinion.

11. Paramecium Lab Counting Stir your cultures. Take one drop out and make a slide Move to the 4 corners of the drop (and cover slide, we will use the small ones) and count the paramecia there. Move to the dead center and count. Record all counts

12. Paramecium Lab There should be two counts done on each culture (two drops looked at). Clarify in your group, who does what.
