Introduction to Ecosystem Review Week
Last week you learned about some of the mass extinctions that have occurred throughout the history of the Earth, and causes for those extinction events. You also learned how biodiversity helps ecosystems, and the threats to biodiversity.
This week is a review for your next test, which covers everything you've learned about ecosystems. The test will include questions about why earth supports life, ecosystems, abiotic & biotic factors, food webs, food chains, and food pyramids, photosynthesis and chemosynthesis, biomes, symbiotic relationships, classification & taxonomy, biodiversity, and extinctions.
Remember, you only get 1 attempt on tests, so be sure to look at the study guide for the exam and play the review game. If you have any questions about any of the information covered in Unit 2: Ecosystems, just let me know! Good luck!
