  • 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
  • 8. An organism's role or how it makes its living 3
  • 9.
    • INCLUDES
    • type of food
    • how it obtains food
    • when and how it reproduces
    • physical conditions needed for survival
    3
  • 10. What are the major types of interactions among organisms? 4
  • 11. Three major types of interactions Competition Predation Symbiosis 4
  • 12. What is COMPETITION? 5
  • 13. The struggle between organisms to survive in a habitat with limited resources. 5
  • 14.  
  • 15. Why can't two species occupy the same niche? 6
  • 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
  • 17.  
  • 18. Describe PREDATION, PREDATOR, & PREY. 7
  • 19. Predation Interaction in which one organism kills and eat another. 7

  • 22.  
  • 23.  
  • 24.

  • 26. The size of the population will decrease. 8
  • 27.  
  • 28. What is SYMBIOSIS? 9
  • 29. A close relationship between two species that benefits at least one of the species. 9
  • 30. What are the three forms of symbiotic relationships? 10
  • 31. Mutualism Commensalism Parasitism 10
  • 32. What is MUTUALISM? 11
  • 33. A relationship in which both species benefit. 11
  • 34. What is COMMENSALISM? 12
  • 35. A relationship where one species benefits and the other species is neither helped nor harmed. 12
  • 36. What is PARASITISM? 13
  • 37. One organism lives on or inside another organism and causes harm. 13
  • 38. Describe PARASITE & HOST. 14
  • 39. Parasite Host The organism that benefits The organism that the parasite lives in or on. 14
  • 40.  
  • 41. A walking stick is an insect that resembles a small twig. How do you think this insect avoids predators? 15
