Across
  1. 3. Movement of individuals into a population
  2. 13. the maximum number of organisms of one species supported by an environment
  3. 16. the number/variety of different species found in an area
  4. 19. competition between members of different species
  5. 20. variable that is manipulated or changed
  6. 21. refers to a population that has no density dependent limiting factors affecting its population growth
  7. 22. movement of individuals out of a population
  8. 23. competition between members of the same species
  9. 24. population growth that is exponential; as the population size gets larger it grows faster
Down
  1. 1. population growth that begins with exponential growth and then levels off to fluctuate around carrying capacity
  2. 2. one type of limiting factor to pop growth; EX: competition, predation, symbiosis
  3. 4. a type of limiting factor to population growth; EX. light, temperature, nutrients, weather, natural disasters, water
  4. 5. the number of individuals in a specific size of area, measure of crowding; 20 rabbits per acre
  5. 6. term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem
  6. 7. something in the environment that slows population growth by increasing deaths or decreasing births
  7. 8. Growth pattern in which a population's growth rate slows or stops following a period of exponential growth
  8. 9. The measurable effect, outcome, or response in which the research is interested
  9. 10. a species that has an unusually large effect on its ecosystem
  10. 11. change in total number of individuals in an area of the same species; determined by number of births minus number of deaths
  11. 12. describes a predator-prey population graph; as prey increases, predator populations increase and as prey decreases, a drop in predator population occurs
  12. 14. the action of a predator chasing, capturing and consuming its prey
  13. 15. indirect effects in a community that are initiated by a predator
  14. 17. Population growth that is unhindered because of the abundance of resources for an ever-increasing population.
  15. 18. individuals of a species leaving or entering a habitat; immigration vs. emigration
