Introduction: During our
study of ecology we will focus on specific relationships between populations
of organisms. Organisms interact in many ways which help to keep their
species’ alive. In the process, populations that are interacted with may be
helped, harmed, or may not experience any impact of the interaction. In this webquest, we will explore many types of interactions
among organisms. |

1. Define the three types of
symbiotic relationships explained here and provide an example of each. 2.
Read the story on the Australian rabbits and explain how the remaining
rabbits changed after the myxoma virus eliminated
almost its entire population. 3.
Read over the section of the evolution of symbiotic relationships. How
do scientists think symbiotic relationships evolved? What two organisms
were involved in the first ever studied primitive type of symbiotic
relationship? |

6.
The man-of-war fishes and the deadly jellyfish is an example of what type of
symbiotic relationship? 7. Give two examples of
mutualism (or symbiosis) and provide the benefits for each organism. 8.
What is an ectoparasite? Give an example of
two organisms that are involved in this type of parasitic relationship. |

10.
Click on “Nectar Guides” under “Pollination symbiosis”. What are the benefits
to the organisms involved?? 11. Click on “Bottle Gentian”
under “Pollination symbiosis”. Why is this such a
great mutualistic association? |

12.
Pick three of the pictures and research those organisms to determine what
symbiotic relationship exists between them. Copy and paste the picture, tell
what organisms are involved, describe the relationship, and classify it as
one of the types of symbiosis we are learning about. a. b. c. |
