Big Ideas
  • Interactions between organisms, such as predation, competition, and mutualism, play a crucial role in maintaining ecosystem balance and health.
  • Changes in ecological relationships can disrupt ecosystem stability and lead to significant consequences for biodiversity and resource availability.
Essential Questions
  • How do different types of ecological relationships influence the stability of an ecosystem?
  • What impact do changes in predation, competition, or mutualism have on ecosystem stability?
  • How can the loss or introduction of a species disrupt existing ecological relationships?
  • In what ways do positive and negative ecological interactions contribute to the resilience of ecosystems?
  • How do scientists investigate and evaluate the role of ecological interactions in maintaining ecosystem health?
