1. Biodiversity and Fossil Record

2. Scenario 1
Mammal and fish populations in marine biomes are decreasing due to lack of oxygen, acidification, and the warming ocean temperatures. This is impacting the food web within oceans.
Increase or decrease of biodiversity?

How can you increase biodiversity?

3. Scenario 2
Fast food places are using areas of land to breed poultry, as well as other organisms. To do this, they are tearing down forests and contaminating the water sources, as well as using up soil.

4. Scenario 3
Within wetlands, people have made laws to protect the area by not allowing animals to be hunted and having more regulations for protection. The wetland wild bird populations have increased over the past thirty years.

7. Create your own fossil record
Layer A: this layer is the second oldest
Layer B: this layer is the second layer from the top
Layer C: this layer has organisms that are most like the organisms today
Layer D: this layer is not as old as layer A, yet older than layer B
Layer E: this layer shares the least amount of similarities with the organisms today

8. Name 3 threats to biodiversity.

9. Name two advantages of biodiversity.

10. What are the two most accurate ways to compare organisms?

11. In a fossil record, where are the oldest organisms located?

12. In a fossil record, where are the youngest fossils located?

13. What are the three types of adaptations?

14. Describe and give an example of a physiological adaptation.

15. Describe and give an example of a structural adaptation.
