2.  Content Area: Science  Grade Level: 5  Summary: The purpose of this Instructional PowerPoint is to help students understand the difference between mutualism, commensalism,and parasitism relationships.  Learning Objective: Given websites that contain facts about symbiotic relationships students will interpret the material within the websites to answer the questions within the PowerPoint with 100 percent accuracy.  Content Standard: GLE 0507.2.2 Explain how organisms interact through symbiotic, commensal, and parasitic relationships.  Accomplishment: 0507.2.2 Classify interspecific relationships within an ecosystem as mutualism commensalism, or parasitism.  SPI 0507.2.2 2 Distinguish among symbiotic, commensal, and parasitic relationships.

3.  Go to this website to explore symbolic relationships http://www.vtaide.com/png/symbiosis.htm http://www.vtaide.com/png/symbiosis.htm  A symbiotic or ecological relationship is a relationship in which two different species of organisms live close together and one member ALWAYS benefits from the relationship.

4.  Go to this website to explore symbolic relationships http://education.nationalgeographic.com/educat ion/activity/ecological-relationships/?ar_a=1 http://education.nationalgeographic.com/educat ion/activity/ecological-relationships/?ar_a=1  There are three types of symbiotic relationships: mutualism, commensalism and, parasitism.  Mutualism- both organisms benefit  Commensalism- one organism benefits while the other is not harmed  Parasitism- one organism benefits at the expense of the other

5. What is symbiotic or ecological relationship? A relationship in which two different species of organisms live close together and one member always benefits from the relationship. A relationship in which two of the same species of organisms live close together and one member always benefits from the relationship

6. Yes, a symbiotic or ecological relationship is a relationship in which two different species of organisms live close together and one member always benefits from the relationship. Mutualism Commensalism Parasitism

7. In what symbiotic or ecological relationship does both organisms benefit? Give an example. Predationism, an oxpecker and an impala Commensalism, barnacle and a whale Mutualism, a sea otter and kelp Parasitism, a tick and a cat or dog

8.  Yes, mutualism is the symbiotic or ecological relationship where both organisms benefit.  Yes, the relation between a sea otter and kelp is an example of the symbiotic or ecological relationship mutualism.

9. In what symbiotic or ecological relationship does one organism benefits while the other is not harmed? Give an example. Parasitism, a braconid wasp and a tomato hornworm Mutualism, an ant and an aphid Predationism, a cattle egret and a cow Commensalism, a clownfish and a sea anemone

10.  Yes, commensalism is the symbiotic or ecological relationship where one organism benefits while the other is not harmed.  Yes, the relation between a clownfish and a sea anemone is an example of the symbiotic or ecological relationship commensalism.

11. In what symbiotic or ecological relationship does one organism benefits at the expense of the other? Give an example. Mutualism, an algae and a fungi Parasitism, a bed bug and a human being Commensalism, a remora and a sea turtle Predationism, a mistletoe and an oak tree

12.  Yes, parasitism is the symbiotic or ecological relationship where one organism benefits at the expense of the other.  Yes, the relation between a bed bug and a human being is an example of the symbiotic or ecological relationship parasitism.

13.  In this lesson the students will learn the definition of symbiotic or ecological relationship.  Students will have learned the three types of symbiotic or ecological relationship.  The student will have learned examples of all three symbiotic or ecological relationships as well.
