Is an extended association between 2 species in a community where at least one of the organisms benefits There are three different types of Symbiosis Relationships, we will examine each of these Symbiosis

The same species compete for resources for survival One species benefits from a relationship with another organism while the other is neither harmed nor benefits Twodifferentspeciesbothbenefitfromhaving a relationship One organism lives on or in another organism and feeds on it, without killing it Two different species compete over resources for survival
Activity: Imaginary Organisms • Break up into groups of 3 • You will be given a set of cards • Each set will contain imaginary organisms with different needs. • Create each of the 5 relationships by matching organisms up based on their needs. • You will need to add information to make the relationships make sense
Research Task • Break up into groups of three • Based on previous lessons, choose an ecosystem that interests you • Research the interactions among organisms found in this ecosystem • Create a poster mapping out these relationships • You will be asked to present your findings to the rest of the class at the end of the lesson
