Symbiosis Readings Set with Worksheets


Students read about examples of mutualism, parasitism, and commensalism.

Grades 6 and Up


This worksheet pairs well with our Symbiosis Worksheet and our Top 10 Weirdest Symbiotic Relationships Article.

High-interest ecology readings about commensalism, mutualism, and parasitism, plus questions and a graphic organizer!

GO PAPERLESS! This activity includes both PDF and GOOGLE SLIDES versions!

In this activity, students will:

  • Read articles with real-life and engaging examples of mutualism, commensalism, and parasitism (8 examples each)
  • Answer text-dependent questions using information from the readings
  • Complete a graphic organizer about the symbiotic relationships from the text

Teacher Notes:

  • This resource does not teach symbiosis. We use it as a reinforcement lesson. There are many ways to incorporate these readings. You might use the readings with your favorite reading strategy – herringbone, chunking the text, etc. It could also be used in a group activity, where groups read just one of the readings and present the information to the whole class orally or in a poster.
