  1. Chapter 1 Vocabulary Review

  2. The behavioral and physical characteristics of a species that allow them to live successfully in their environment. • Adaptation

  3. An interaction in which one organism kills and eats another organism • Predation

  4. A close relationship between two species that benefits at least one of the species. • Symbiosis

  5. The organism that benefits in parasitism • Parasite

  6. Moving into a population • Immigration

  7. A relationship in which both species benefit • Mutualism

  8. The process in which organism make their own food using water, sunlight, and carbon dioxide • Photosynthesis

  9. The organism that is harmed in parasitism • Host

  10. An approximation of a number, based on reasonable assumptions. • Estimate

  11. The organism that does the killing • Predator

  12. The series of changes that occur in an area where the ecosystem has been disturbed, but where soil and organisms still exist. • Secondary Succession

  13. Living parts of an ecosystem • Biotic factors

  14. The series of predictable changes that occur in a community over time • Succession

  15. The number of births in a population in a certain amount of time. • Birth rate

  16. A group of organisms that are physically similar and can mate with each other and produce offspring that can also mate and reproduce. • Species

  17. The first species to populate the area • Pioneer species

  18. Moving out of a population • Emigration

  19. A relationship in which one species benefits and the other is unaffected. • Commensalism

  20. The number of individuals in a specific area • Population density

  21. Series of changes that occur in an area where no soil or organisms exist • Primary Succession

  22. The struggle between organisms to survive as they attempt to use the same limited resource. • Competition

  23. A relationship in which one organism benefits and the other is harmed. • Parasitism

  24. All the different populations living together in an area • Community

  25. An organism’s particular role in its habitat, or how it makes a living • Niche

  26. A method used to determine population size using the following formula:Total population =(number of total individuals captured X number of originally marked ) Total number of individuals recaptured with mark • Mark and Recapture

  27. An environmental factor that prevents a population from increasing • Limiting factor

  28. The organism that is killed • Prey

  29. Counting every organism that you see to determine population size • Direct observation

  30. The process by which characteristics that make an organism better suited for their environment become more common in that species. • Natural Selection

  31. The place where an organism lives and that provides the things the organism needs to survive. • Habitat

  32. Counting signs of an organism to determine population size • Indirect observation

  33. Counting the number of individuals in a small area and then multiplying to find the number ina larger area • Sampling

  34. All living things • Organisms

  35. The study of how living things interact with each other and with their environment. • Ecology

  36. The largest population that an environment can support • Carrying capacity

  37. All the members of one species in a particular area • Population

  38. Nonliving parts of an ecosystem • Abiotic factors

  39. The levels of ecological organization from smallest to largest. • Organism, population, community, ecosystem

  40. The Great Oyster Sampling…. OYSTER BED... 100 meters wide X 50 meters = ?? There are 20 oysters per square meter, so how many oysters would be in an area this size?

  41. First find the area of the PRETEND OYSTER bed…. • 100 meters X 50 meters = 5,000 meters squared • Then multiply your SAMPLE SIZE by your AREA SIZE…. • 5,000 meters squared X 20 oysters per square meter = 100,000 oysters!!
