  1. Types of Relationships

  2. Predation • An interaction in which one organism kills another for food • Ex: green tree python eats a mouse

  3. The struggle between organisms to survive as they attempt to use the same limited resources Some species will adapt so that they may coexist. Komodo Dragon Competition

  4. SYMBIOTIC RELATIONSHIPS • SYMBIOSIS is the interaction between two different organisms that benefits at least ONE • HOST- usually the LARGER of the 2 organisms • SYMBIONT- usually the SMALLER member

  5. THE THREE SYMBIOTIC RELATIONSHIPS ARE... Click on a Picture Below to Learn About the Relationship PARASITISM MUTUALISM COMMENSALISM EXTRA PRACTICE ACTIVITY GO BACK TO SPECIFIC QUESTION EXIT

  6. Mutualism • Is a relationship between the host and a symbiontwhere BOTH organisms benefit and neither is harmed. • The relationship can be long or short term. EXIT

  7. COMMENSALISM • Is a relationship between the host and symbiont, where the symbiontbenefits and the host is neither helped nor harmed. • The symbiont benefits by receiving transportation, housing, and/or nutrition. EXIT

  8. PARASITISM • Is a relationship where the Symbiont lives in/on the Host • The Symbiont (or Parasite) BENEFITS • The Host is HARMED EXIT

  9. EXTRA PRACTICE ACTIVITY In the following activity, you will be given a picture scenario. Identify and select the symbiotic relationship (parasitism, mutualism, or commensalism) represented in the picture. EXIT

  10. In this photo the “cleaner fish” receives nourishment by dining off of the parasites and remaining food debris in the eel’s mouth. Is this an example of… PARASITISM MUTUALISM COMMENSALISM EXIT

  11. That’s CORRECT! Keep up the great work! EXIT

  12. SORRY MAN, TRY AGAIN SORRY MAN, TRY AGAIN EXIT

  13. The birds in the picture are munching on tiny parasitic insects located on the rhino. The relationship between the birds and the rhino is an example of… PARASITISM MUTUALISM COMMENSALISM HELP EXIT

  14. SORRY MAN, TRY AGAIN EXIT

  15. That’s CORRECT! Keep up the great work! EXIT

  16. Lampreys are primitive fish with limited digestive systems. They attach to and feed on the body fluids of fish with more advanced digestive systems, often leading to the death of the host fish. This relationship is an example of… PARASITISM MUTUALISM COMMENSALISM HELP EXIT

  17. SORRY MAN, TRY AGAIN SORRY MAN, TRY AGAIN EXIT

  18. That’s CORRECT! Keep up the great work! EXIT

  19. Orchids grow on the branches of high trees. These orchids get more water and sunlight than those on the ground. The tree is unaffected by the orchid’s presence. This relationship is an example of… PARASITISM MUTUALISM COMMENSALISM EXIT HELP

  20. SORRY MAN, TRY AGAIN SORRY MAN, TRY AGAIN EXIT

  21. That’s CORRECT! Keep up the great work!

  22. The zebra benefits by having the oxpecker eat the ticks & parasites off the zebra. PARASITISM MUTUALISM COMMENSALISM EXIT

  23. SORRY MAN, TRY AGAIN SORRY MAN, TRY AGAIN EXIT

  24. That’s CORRECT! Keep up the great work! EXIT

  25. Mistletoe is a plant that grows on other plants/trees. The mistletoe takes water and nutrients from the host tree sap for growth and development. The host tree is not immediately killed, but can be weakened and will become susceptive to breakage, rotting, and fungi PARASITISM MUTUALISM COMMENSALISM EXIT

  26. SORRY MAN, TRY AGAIN EXIT

  27. That’s CORRECT! Keep up the great work! EXIT

  28. The hookworm feeds on the nutrients in the intestines. The human is harmed because the hookworm takes away important nutrients. PARASITISM MUTUALISM COMMENSALISM EXIT

  29. SORRY MAN, TRY AGAIN SORRY MAN, TRY AGAIN EXIT

  30. That’s CORRECT! Keep up the great work! EXIT

  31. Cattle Egrets live in many pastures occupied by livestock. When the livestock move about the pasture, they kick up bugs and insects. The cattle egrets feed on these bugs. The livestock does not necessarily benefit from this relationship, nor are they harmed. PARASITISM MUTUALISM COMMENSALISM EXIT

  32. SORRY MAN, TRY AGAIN EXIT

  33. That’s CORRECT! Keep up the great work! EXIT

  37. THE END EXIT

  38. How did the Isle Royale moose population change between 1965 and 1972? • How did the wolf population change between 1973 and 1976? • How might the change in moose population have led to the change in the wolf population? • What is one likely cause of the dip in the moose population between 1974 and 1981? • How might disease in the wolf population one year affect the moose population the next year? • How are the wolf and moose populations related?

  39. After the hare population increased, what happened to the lynx population? Why? • How do you think an increase in the lynx population affected the hare population? Why? • What other factors could have caused a decrease in the hare population? • Predict what happened to the two populations between 1935 and 1945.
