Describe two different organisms that depend on each other for their survival. What are these? • S7L4d categorize relationships between organisms This is another of our Georgia Performance Standards. http://www.georgiastandards.org/ http://www.cobbk12.org/~daniell/ 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. Lion King Video Clip Pay attention to all the different animals and plants that you see or hear. On the left Organisms in list them here with commas organism one, two, etc Lion King: Share your list with the person next to you. Don’t write this. 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? Friday Sept. 3rd No Response Page today. . Pull out the Cornel Notes we started yesterday and be ready to finish these when the bell rings -This means, paper is out, pencil is sharp and ready to go. 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 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 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. Cornell Notes – Summary do not write this page of notes 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.
