Anouncements
Today Mr. Peak started out by telling us important anouncements. The oil spill project was originally due on Thursday, 9/23 but it is now due on Friday, 9/24 because we will not watch the videos until friday. The invading species project is due on Monday, 9/27. After that Mr. Peak told us how to load your oil spill project as a blog.
Posting Video on Blogger
First log on to blogger and click on new post.
Then enter the name of the project in the title box and the view you choose for the second half of the photos. For example if its about a fishermans point of view put (Oil Spill and fishermans view).
Next on the top bar with all the gadets click on (add video) it looks like a film role. Make
sure you save it as a movie maker video. Upload video and then you will need to fill in the
lable as (OilSpill, and the screenames of your partners).
Human Impacts
Biological Magnification
-Phenemenon in which cocentration of certain compounds in organisms of a food chain increases as you moce up the food chain
This photo represents biological magnification. In the photo the zooplankton eat the ddt as the they get eaten and the bigger fish get eaten the amount of ddt in the final host will have gotten much higher because as each prey get eaten the more they eat the more that it really affects the last animal compared to the first. So in the end the bird will have the most ddt and the zooplankton will have the least.
