  2. Herbivores

  3. Carnivores

  4. Predator/Prey

  5. Amanita muscaria Adaptation to Predation

  6. Commensalism

  7. Mutualism

  8. Coral polyps

  9. Mutualism + Commensalism = Symbiosis

  10. Parasitism

  11. Rafflesia, world’s largest flower Rafflesia is the world’s largest flower which belongs to the genus of parasitic flowering plants.
