1.3 Interactions Among Living Things

  1. 1. Interactions Among Living Things Mr. Schumaier
  2. 2. What are ADAPTATIONS? 1
  3. 3. Behaviors and physical characteristics of species that allow them to live successfully in their environment 1
  4. 4. How do an organism's adaptations help it to survive? 2
  5. 5. An organism's adaptations enable it to fill a unique role in its ecosystem—eating particular types of food, obtaining its food in unique ways, and using other abiotic and biotic factors to meet its needs 2
  6. 7. What is a NICHE? 3
  7. 8. An organism's role or how it makes its living 3
  8. 9. <ul><li>INCLUDES </li></ul><ul><li>type of food </li></ul><ul><li>how it obtains food </li></ul><ul><li>when and how it reproduces </li></ul><ul><li>physical conditions needed for survival </li></ul>3
  9. 10. What are the major types of interactions among organisms? 4
  10. 11. Three major types of interactions Competition Predation Symbiosis 4
  11. 12. What is COMPETITION? 5
  12. 13. The struggle between organisms to survive in a habitat with limited resources. 5
  13. 15. Why can't two species occupy the same niche? 6
  14. 16. If two species try to occupy the same niche, they will compete directly against each other, and one species eventually will die off. 6
  15. 18. Describe PREDATION, PREDATOR, & PREY. 7
  16. 19. Predation Interaction in which one organism kills and eat another. 7
  17. 20. Predator The organism that does the killing 7
  18. 21. Prey The organism that is killed 7
  19. 25. If predation removes more members of a population than are born, how will the population change? 8
  20. 26. The size of the population will decrease. 8
  21. 28. What is SYMBIOSIS? 9
  22. 29. A close relationship between two species that benefits at least one of the species. 9
  23. 30. What are the three forms of symbiotic relationships? 10
  24. 31. Mutualism Commensalism Parasitism 10
  25. 32. What is MUTUALISM? 11
  26. 33. A relationship in which both species benefit. 11
  27. 34. What is COMMENSALISM? 12
  28. 35. A relationship where one species benefits and the other species is neither helped nor harmed. 12
  29. 36. What is PARASITISM? 13
  30. 37. One organism lives on or inside another organism and causes harm. 13
  31. 38. Describe PARASITE & HOST. 14
  32. 39. Parasite Host The organism that benefits The organism that the parasite lives in or on. 14
  33. 41. A walking stick is an insect that resembles a small twig. How do you think this insect avoids predators? 15
  34. 42. By staying motionless among a plant's branches, the walking stick is camouflaged and cannot easily be seen by predators. 15
  35. 44. The End
