Interactions are a way of life. All organisms interact with many other organisms on a daily basis. Some of these interactions are positive, benefitting all organisms involved. Some of these interactions are negative, which may cause harm. Plants, animals and all other living things interact, and these many interactions are readily observable in our own backyards. In this activity we will explore these interactions and predict how they will help or harm species when their environment changes (biotic or abiotic changes).

At the conclusion of the lesson, students will be able to:

  • Identify interactions between different species (observation)
  • Name and describe the different types of species interactions
  • Recognize that species may develop more than one relationship
  • Predict the impact of environmental changes (biotic or abiotic) on the relationship or individual organism
