CH 18 Test

Chapter 18 is large, but a lot of the concepts come in chunks. Type of consumers (herbivores, omnivores, carnivores & scavengers) for instance. Or Levels of Environmental Organization from the large Biosphere and Ecosystems, on down to Communities, Populations and Individual Organisms.

This video is longer to take the time to cover these and other concepts. Additionally you be asked to calculate energy loss in an Energy Pyramid (like we did in CH18-2), I give 2 examples and you'll be able to use a calculator if needed. Lastly you'll be given 1 of 4 food webs to use during the test. They're in the video if you'd like to see them ahead of time.

Extra Credit will come from one of the following videos.
