Understanding Commensalism: Adaptations in Nature

This lesson explores commensalism and its relationship with other ecological interactions like parasitism and mutualism. Students will identify and understand structural and behavioral adaptations of various organisms, including the puffer fish, roses, and sharks. Drawing on textbook resources, learners will give examples of how specific creatures adapt to their environments. The session concludes with an exit question where students will select one animal to describe both its structural and behavioral adaptations, emphasizing the importance of adaptation in survival.

  1. Bell Ringer What is commensalism?

  2. Today • Bell Ringer • Chapter 3 Lesson 3 • Chapter 3 Lesson 4 • I CAN GIVE 1 EXAMPLE FOR A STRUCTURAL ADAPTATION. • I CAN GIVE 1 EXAMPLE FOR A BEHAVIORAL ADAPTATION. • Don’t forget Monday’s homework due on Wednesday.

  3. Your Topic Goes Here • Yesterday: commensalism, parasitism, mutualism • What do ALL of these • have in common?

  4. What is adaptation? • Structural—adjustments to internal or external physical structures • Some of these help adaptations help organisms survive in certain environments.

  5. Use the book to find the structural adaptations for each of the following: • 1. puffer fish • 2. roses • 3. cactus • 4. ducks • 5. turtles • 6. sharks • 8 minutes

  6. Behavioral adaptations– adjustment in an organism’s behavior. • Examples include: wolves traveling in packs, that look from Mrs. Longworth, fish swimming in schools

  7. Today: • Read pages 168-172 • Exit question: • Put your name at the top and turn in as you go out the door.

  8. Choose 1 animal and give a structural adaptation and a behavioral adaptation for the chosen animal.
