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