Why Can’t We All Just Get Along? How can we find out?
What we Know Predator and Prey Relationships Predator eats the prey Prey is what is eaten What we Wonder about Predators and Preys What defense mechanisms do animals exhibit? What is symbiosis? What is commensalism? What is mutualism? What is parasitism? What we Learned about Predator and Prey Relationships How does commensalism, mutualism and parasitism affect predator and prey relationships?
What We Know About Predator and Prey Relationships? Predator eats the prey Prey is what is eaten The prey develops defense mechanisms to prevent being eaten http://www.desertusa.com/may96/du_rattle.html
Why are predators-prey relationships important to us? www.thewebscenes.co
What is Symbiosis? Living together in close association of organisms of two different species. RHINO AND OXPECKER www.thewebscenes.co
What is Commensalism? A symbiotic relationship in which one organism is helped and the other is neither helped nor harmed. GULL/BROWN BEAR www.thewebscenes.co
What is Mutualism? A close relationship between two organisms which is helpful to both organisms. OSTRICH/GAZELLE www.thewebscenes.co
What is Parasitism? A symbiotic relationship in which one organism, the parasite, spends much or all of its life in or on another organism, the host. The parasite is dependent upon the host for food. The parasite benefits from the relationship, and the host is always harmed. www.thewebscenes.co
To answer our Wonder questions we need to…. 1. Read aloud the book, What do you do when something wants to eat you? 2. View Photo Story (Sea Lamprey-Fish) 3. View card game of symbiotic relationships 4. Do research on predator-prey relationships 5. Give the common and scientific names of the organisms involved in your interaction 6.Work on predator-prey databases 7. Work on spreadsheet on predator-prey relationships 8. Play Population Dynamics Card Game
Let’s brainstorm what we think about… Predator and Prey Relationships: helpful harmful Commensalism Mutualism Parasitism
