  3. Literal definition:the act of living together What is symbiosis? What it means: Two organisms that live together Temporarilyor for a longer time At least one of theorganisms benefits from the relationship

  4. Mutualism Commensalism What are the different kinds of symbiosis? one organism benefits one organism benefits both organisms benefit Parasitism one organism is unaffected one organism is harmed

  5. Example 1:Acacia plant with ant galls Ants lay eggs on acacia treeAcacia covers the infected area withbrown flesh (gall) Parasitism: one benefits, one is harmed

  6. Example 2:Moray Eel with Cleaner Fish Mutualism: both benefit Moray Eel gets a clean mouth Cleaner Fish gets a meal

  7. Example 3:Cattle with cattle egrets Cattle stir up insects as they eat grassEgrets hangaround and eat insects Commensalism: one benefits, one is unaffected

  8. Example 4:Clown fish with anemone Clown fish gets protection Anemone gets food Mutualism: Both benefit

  9. Example 5:Antelope with Oxbird Antelope getsrid of parasites Oxbird gets a meal Mutualism: both benefit

  10. Example 6:Taenia worm in human eye Worm infects humanblood streamHuman may go blind Parasitism: one benefits, one is harmed
