Symbiosis is an interaction between organisms where they are so dependent on each other they are nearly as one. This power point covers endosymbiosis, mutualism, commensalism, parasitism, predation and free living organisms. There are examples of each.
Students will be able to determine the types of symbiosis organisms are engaged in. I have another power point called Symbiosis Quest Power Point which is an activity where students have to identify the type of symbiotic relationship. It is a great follow up activity to this lesson.

GREAT FOR ANY STATE!

(12) Science concepts. The student knows that interdependence and interactions occur within an environmental system. The student is expected to:
(A) interpret relationships, including predation, parasitism, commensalism, mutualism, and competition among organisms;

MS-LS2-1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
MS-LS2-2. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems. [Clarification Statement: Emphasis is on predicting consistent patterns of interactions in different ecosystems in terms of the relationships among and between organisms and abiotic components of ecosystems. Examples of types of interactions could include competitive, predatory, and mutually beneficial.]
