  3. 7. interacting groups of various species in one ecological niche
  4. 8. interspecific interaction where two or more species fight for resources
  5. 9. formula (relying on the capture recapture method) to determine population size
  6. 14. type of interspecific relation where one organism feeds on another without killing the host
  7. 15. the number of births within a population, in a period of time
  8. 17. example of interspecific relations, where bees take pollen from flowers
  9. 19. idea that a community is regulated by the beginning of a food-chain (ie, grass regulates a community)
  10. 20. the period of time in population growth where the number of members of a species regularly increase

Down
  1. 1. Type of sampling where an area is divided into squares that are analyzed, these squares are usually chosen at random based on the width and length of the area
  2. 4. method of competition (between plants)where toxins are released in an environment to curb competition
  3. 5. type of interspecific relationship where two organisms both get benefits from the relationship
  4. 6. Selection of a part of the population to observe so that one of many estimate the whole population

  8. 13. organism that consumes both animals and plants as its food-source
  9. 16. idea that a community is regulated by the end of a food-chain (ie, wolves regulate a community)
  10. 18. an animal (or other organism) that consume plants as the its main food source
  11. 21. Interspecific symbiotic relationship between plants and fungi, where plant roots are aided with nutrition from fungi
