Biodiversity and Symbiosis Notes

Key Concepts of Symbiosis

• Definition of Symbiosis: A biological term that describes the interaction between two different organisms, which can be beneficial, harmful, or neutral to one or both.

• Types of Symbiosis:

  • Mutualism: A type of symbiosis where both organisms benefit from the interaction.
  • Example: Dogs and their owners. Dogs provide companionship while owners offer food and shelter.
  • Commensalism: One organism benefits while the other is unaffected.
  • Example: Barnacles on whales. Barnacles get a place to live and feed, while whales are neither helped nor harmed.
  • Parasitism: One organism benefits at the expense of the other.
  • Example: Ticks feeding on dogs. Ticks gain nutrients and a habitat, while dogs suffer harm from feeding.

Mini Research Project Instructions

• Objective: Find an example of one of the three types of symbiosis.
• Tasks:
  • Research one type of symbiosis (mutualism, commensalism, or parasitism).
  • Answer the provided questions on your paper related to the example.
  • Create a diagram to visually represent the symbiosis interaction.
• Duration: You have approximately 8 minutes to complete the research and diagram.

Additional Notes

• Use your phones for research, ensuring that all students understand how to proceed.
• Engage in pairs or groups to facilitate sharing of ideas and information.
• Ensure to record findings clearly as they will be shared later.
