  1. Ecosystems 2 SOL #11 TSW differentiate between symbiosis, mutualism, commensalism, and parasitism

  2. Cornell Notes • Blue – Left side of the line • Black– Right side of line • Orange– Notes not required • Red – Review questions (notes not required)

  3. 25. What is predation? • Interaction in which one organism kills another for food

  4. 26. Examples of predator adaptations Cheetahs - aerodynamic • Sticky sundew on a Venus flytrap attracts insects • Owls can hunt at night (nocturnal)

  5. 27. Examples of prey adaptations Protective Coverings – Sea Urchin Camouflage – Preying Mantis Warning Colors – Arrow Frog False eye – Butterfly Fish

  6. Examples of prey adaptations Mimicry -use of colors and markings to look like another animal(imitate - mimic) Bee fly mimics the coloration/ appearance of a stinging bee Moth caterpillar defends itself by mimicking a snake

  7. Mimicry – Which is poisonous? Desert King Snake Coral Snake - Mountain King Snake

  8. 28. What is Symbiosis? A close relationship between two species that benefits (+) at least one of the species 29. Three types of symbiotic relationships Mutualism, Commensalism, Parasitism

  9. 30. What is Mutualism? • a relationship in which two organisms interact and BOTH receive a benefit • Mutually beneficial relationship (+, +) 31. Examples of mutualism • Moray eel (+ gets a clean mouth) and the cleaner fish (removes parasites – + gets food)

  10. 32. Examples of mutualism • Shark (0) and a suckerfish (+) (eats the scraps) – ex. Not mutualism it’s Commensalism • Rumen Bacteria in cow’s • stomach • food and home for the • bacteria (+) • helps cow (+) digest grass and hay

  11. No, a skate board and a girl are not an example of mutualism Is this an example of mutualism? Why not? A skate board is abiotic

  12. 33. What is commensalisms? • a relationship between two species in which one species benefits, while the other is neither harmed nor helped (+, 0) 34. Give an example • Squirrel (+) living in a tree(0)

  13. 35. What is parasitism? • an organism (parasite) that lives on or in another organism (host) • Parasite receives the benefit while the host is harmed or destroyed (+, -)

  14. 36. Give examples • Tapeworm (+) and human (-) • Aphids (+) and rose bush (-) • Termites (+) and tree (-)

  15. 1. Predation 2. Symbiosis 3. Mimicry a. Use of colors and markings to look like another animal b. A close relationship between two species that benefits at least one of the species c. Interaction in which one organism kills another for food Review Questions – Match the key word/s with the definition

  16. 4. Parasitism 5. Mutualism 6. Commensalism d. BOTH organisms receive a benefit e. 1 organism receives the benefit while the other is harmed or destroyed f. 1 organism receives a benefit, while the other organism is unaffected g. (+, +) h. (+, 0) i. (+, -) Review Questions – Match the key word/s wit the definition

  17. A tick and a dog • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  18. 1. A tick and a dog • 1. Tick (+) / Dog (-) • Parasitism

  19. 2. Spanish Moss (flowering epiphyte) growing on an Oak tree • 2. + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  20. 3. Ants help protect aphids from predators and in return the ants get honeydew from the aphids • 3. + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  21. 4. Bee and a flower • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  22. 5. Whale and Barnacles • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  23. 6. Rhinoceros and Redbilled Oxypecker • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  24. 7. Trout and Sea Lamprey • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  25. 8. Epiphyte plant on a Rainforest tree • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  26. 9. Lichen • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism

  27. 10. Strangler fig and another tree • + / +, + / O or + / - • Mutualism, Commensalism or Parasitism http://www.youtube.com/watch?v=UCUtpmwacoE

  28. 2. Spanish Moss (flowering epiphyte) growing on an Oak tree • Spanish Moss (+) / Oak Tree (O) • Commensalism

  29. 3. Ants help protect aphids from predators and in return the ants get honeydew from the aphids • Ants (+) / Aphids (+) • Mutualism

  30. 4. Bee and a flower • Bee (+ ) / Flower (+) • Mutualism

  31. 5. Whale and Barnacles • Barnacles (+) Whale (O) • Commensalism

  32. 6. Rhinoceros and Redbilled Oxypecker • Oxypecker (+) / Rhino (O) • Commensalism

  33. 7. Trout and Sea Lamprey • Sea Lamprey (+) / Trout (-) • Parasitism

  34. 8. Epiphyte in the Rainforest tree • Epiphyte (+ ) / Tree (O ) • Commensalism

  35. 9. Lichen - Fungus serves as structural support and provides moisture (prevents lichen from drying out during dry weather) Algae produces food for itself and fungus (photosynthesis) • Fungus (+ ) / Algae ( + ) • Mutualism

  36. 10. Strangler fig and another tree • Strangler (+ ) / Tree (-) • Parasitism http://www.youtube.com/watch?v=UCUtpmwacoE
