  1. Interactions Among Organisms How do organisms act when they are around each other?

  2. INTERacting • Interactions between living things help maintain BALANCE in an ecosystem. • Every organism has a variety of ADAPTATIONS that are suited to its specific living conditions. • Q: Name an example of how two types of organisms interact.

  3. 3 Types of Interactions • Competition • Predation • Symbiosis

  4. Competition • When organisms struggle to survive in a habitat with limited resources. • Why can’t all organisms survive and share the resources?

  5. Predation:(Predator vs. Prey) • When one organism (predator) kills and eats another organism (prey) • How does predation affect population size?

  6. Predators Run fast Camouflage Claws, talons, teeth Strength Prey Run fast Warning Coloring Camouflage Armor Mimicry False Coloring Adaptations

  7. Mimicry Examples Coral snake King snake

  8. Mimicry Examples Viceroy butterfly Monarch butterfly

  9. Symbiosis • A close relationship between two different species that benefits at least one of the species • 3 Types of Symbiosis: • Mutualism • Parasitism • Commensalism

  10. Mutualism • Both organisms benefit • Examples: • Flower and bumblebee • Humans and intestinal bacteria

  11. Parasitism • One organism benefits, the other is harmed • Examples: -Hornworm and wasps -Ticks and dogs

  12. Commensalism • One organism benefits, the other is unaffected • THIS IS NOT VERY COMMON IN NATURE!! (Why???) • Examples: • Bird’s nest and tree • Mites on a damselfly • Shark and remora fish
