  1. Relationships Between Organisms Dynamic Ecosystems – Unit 2 AOS 2

  2. Aims • To describe the five key relationships between organisms found in ecosystems • To be able to apply this knowledge in a novel setting • To investigate interactions among organisms in an ecosystem of choice

  3. Relationships 1a and 1b

  4. Two types of competition

  5. Relationship 2

  6. Video

  7. Adaptations to overcome predators

  8. Monarch Butterfly (bad taste) Viceroy Butterfly

  9. 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

  10. Relationship 3

  14. Relationship 5

  16. Oneorganismkills and feeds off anotherorganism. 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

  17. 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

  18. 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
