Symbiotic relationship
Introduction: Living creatures -- both plant and animal -- frequently exhibit unusual
partnerships. In some associations, both benefit. In others, one species gains more than
the other. In symbiosis, two or more species live together in a close relationship. There
are basically three types of symbiotic relationships: mutualism, commensalism, and
parasitism. Your mission is to become experts on these three types of symbiotic
relationships.
.
Task: You will work in pairs to explore and research information about the three types of
symbiotic relationships: mutualism, commensalism, and parasitism.
1: Define: Mutualism, Commensalism and parasitism
2: Give examples of each type of relationship.
3: Answer the question: The year is 2800 in a galaxy far, far away. You are a symbiont
in search of a humanoid (used to describe a being from another planet that has the
appearance or characteristics of a human) in order to form a symbiotic relationship.
What type of relationship would you form? (mutualistic, commensalistic, parasitic) What
would you look like? How does your relationship impact the humanoid? Write a science
fiction story about your life as a symbiont and illustrate it!

Conclusion: All living species interact with other species. Some of these relationships
are beneficial and some are not. Can you think of other symbiotic relationships in your
everyday life? Are they mutualistic, commensalistic, or parasitic?
