Review of Class - September 14, 2011

In Biology today, we first did a reading check of 4.2. Next Mrs. Stein talked about our upcoming ecology quiz that will be on Thursday. She said, if you want to know what will be on the quiz, log on to Moodle, go to STS Biology, on the far right hand side, there will be a calendar, click on September and click on Ecology Quiz. It will take you to a page that lists what will be on the quiz. Next, we talked about our homework. We have to read section 5.1 and 5.2 and make up six different questions and answers! After we talked about homework for tomorrow, we took some notes about Community Interactions. Below are the notes:

Predation: An organism that kills and feeds on another organism.

Symbiosis: Organisms that are "living together"

Mutualism: When both of the species benefit from the relationship

Commensalism: When one species benefits, but the other one is not harmed in any way.

Parasitism: One of the species benefits from the relationship, but the other one is harmed.

Niches

Niches are physical and biological conditions of an organism.

Niches play an important role in the food chain and the ecosystem.


After we finished the notes, we got with our lab groups and checked where we are in our duckweed presentations and we also filled out a sheet on who is doing what in the presentation.

Thank you and have a great day!

THE NEXT SCRIBE WILL BE... KAILY.
