On a new response page R.P. Describe two different organisms that depend on each other for their survival. Today in Science: •Organisms’ Interdependence: Cornell notes •S7L4d categorize relationships between organisms •Finish “Deer of Kaibab” •Exit Pass Food Webs •HW study for Wed. quiz What are these? • S7L4d categorize relationships between organisms • S7CS1a keep honest, clear, and accurate records These are two of our Georgia Performance Standards. http://www.georgiastandards.org/ http://www.cobbk12.org/~daniell/ http://www.team7-2.org/ Does everyone know how to get to Daniell’s site? Organisms’ Interdependence: Cornell notes • Cornell notes are a type of two column notes. • Questions are on the left and the major notes are on the right side. • You can write questions as you go, or as you reread notes add questions. Types of Questions: What I still do not understand. What else I’d like to know. A good test question. What is a population? Number of one species that lives in an area. What are limiting factors? Food, water, living space and other resources that limit the size of a population What is the The largest population an Carrying capacity? environment can support. Lion King Video Clip http://www.youtube.com/watch?v=km_Yeadze0c Pay attention to all the different animals and plants that you see or hear. On the left Organisms in list them here animal one, two, etc Lion King: Share your list with the person next to you. How do the organisms interact? • There are three main ways that organisms interact. Some organisms pretty much are dependent on another for survival. Any ideas? Back to your notes Describe how 1. Predation – relationship where one animal hunts Organisms and kills for food. Interact? predator – organism that kills and eats another. predator adaptations – speed, sharp teeth & claws. ex. Lions Coral snake prey – organism that is killed and eaten. (din din) prey adaptations – stay in groups, camouflage, warning color, defensive chemicals, shells ex. Deer, turtles pg 492-493 Scarlet king snake 2. Competition – two or more organisms trying to use the same limited resources. ex. Squirrels and chipmunks ex. Plants competing for sunlight p 491 NO RP • Take 5 minutes to update your T of C • Late work – 11 Vocab words which are on Friday’s test – Directed Reading NB#14 • Turn in the Relationships Ecosystems (the page with the bear on it – if you are done back too) Pull out your NB # 9 – Cornell Notes We are still not finished Stopped Here with 6th 3. Symbiosis – a close long term relationship between two organisms where at least one benefits. Don’t write this Mutualism, commensalism parasitism – sounds like? a. mutualism – both benefit. Describe the 3 types of Symbiosis? ex. Egret and rhino 3 types of Symbiosis continued b. commensalism – only one benefits; other is not harmed or helped. ex. Hawk and cactus remora and shark 3 types of Symbiosis continued c. Parasitism relationship between two species in which one species, the parasite benefits from the other species the host which is harmed ex flea (parasite) dog (host) kudzu (parasite) oak tree (host) P 495 What is Coevolution? Long term change that takes place in two species because of their close interactions with one another. Ex ants and acacia tree pg 495 Cornell Notes - Summary The professor at Cornell who is credited with these notes learned that if he didn’t make his college students stop, re-read notes and summarize, these young adults didn’t remember the material as well. So, future college students, take a few minutes to read over every word, then write a summary in the summary section. What type of interaction is . . . • Nemo (clown fish) and anemone? – Symbiosis - mutualism • Tapeworm and cats? – Symbiosis - parasitism • Sea anemone and jellyfish? – predation • Corals and algae? – Symbiosis - mutualism • Corals and tiny shrimp? – predation • Pull out the video notes from Friday that you did for Mrs. Goldman and Mr. Gust – NB# 13 • Write 1 – 8 either at the bottom or on the back. • Listen to the examples and write the two organisms and what type of interaction each is. This will be turned in today. • ..\..\..\..\Documents and Settings\homeuser\Desktop\Ecology 2\Raymond Interactions.wmv Homework • Study your Ecology Vocabulary for a test this Friday. It is just vocab but it is all 25 words – and some of you have not even defined those words).
