  2. Science • Grade Level: 5th • Summary: The purpose of this powerpoint is to inform students about interspecific relationships between organisms within an ecosystem. (i.e. mutualism, commensalism, parasitism) • Learning Objective: Given the information in the Powerpoint presentation, students will answer the given questions with 100% accuracy. • Content Standard: GLE 0507.2.2 Explain how organisms interact through symbiotic, commensal, and parasitic relationships. • SPI 0507.2.2 Distinguish among symbiotic, • commensal, and parasitic relationships.

  3. Interspecific Relationships • There are many organisms in each ecosystem. Different species of organisms interact with each other through various interspecific relationships. Today we are learning about symbiotic relationships. These include… • Commensalism • Mutualism • Parasitism

  4. Symbiotic Relationships • Use the link below to understand the definition of a symbiotic relationship. • http://www.thefreedictionary.com/Symbiotic+Relationships

  5. Commensalism • One organism benefits from the relationship while the other organism neither benefits nor is harmed.

  6. Mutualism • A relationship in which both organisms benefit each other.

  7. Parasitism • In a relationship of parasitism, one species harms the other in order to benefit itself.

  8. Symbiotic Relationships • This website shows good interactive examples of mutualism, commensalism, and parasitism. • http://www.vtaide.com/png/symbiosis.htm

  9. Symbiotic Relationships • ://www.youtube.com/watch?v=zSmL2F1t81Q&noredirect=1 • Watch this video about symbiotic relationships in an underwater ecosystem.

  10. Select the Correct Answer • What is a close, prolonged association between two or more different organisms of different species that may, but does not necessarily, benefit each member? Symbiosis Mutualism Commensalism Parasitism

  11. Select the Correct Answer • What type of relationship does the clownfish have with the anemone? Mutualism Commensalism Parasitism

  12. Select the Correct Answer • Which is an example of parasitism? A bird eating insects off of a buffalo. A tic on a dog’s ear. A shrimp removing parasites from a fish.

  13. Select the Correct Answer • What is an example of mutualism? Barnacles anchored to a whale for food. Otters who lie on kelp and eat animals that would eat the kelp. Bed Bugs.

  14. Bonus Question! • What famous cartoon fish lived in a mutualistic relationship with his own house? • Hint: He lived there with his dad…

  15. NEMO!

  16. Summary • The students have watched a video and gone to websites to learn about symbiotic relationships. They should now have a better understanding of mutualism, commensalism, and parasitism. They also answered questions to exercise their new knowledge.
