Across
- 2. potential / The maximum capacity of an individual or population to reproduce under optimal environmental conditions
- 3. capacity / represents the largest number of individuals that a given environment can support
- 6. competition / an interaction in population ecology, whereby members of the same species compete for limited resources
- 8. diagram / graph of the numbers of males and females within different age groups of a population
- 9. resistance / the sum of the environmental factors (such as drought, mineral deficiencies, and competition) that tend to restrict the biotic potential of an organism or kind of organism and impose a limit on numerical increase.
- 11. distribution / the natural arrangement and apportionment of the various forms of animals and plants in the different regions and localities of the earth.
- 15. growth / occurs when the individuals in a population reproduce at a constant rate
- 17. factor / a factor that causes population growth to decrease
Down
- 1. growth / occurs when a population's growth slows or stops following a period of exponential growth (S-shaped curve)
- 4. / the movement of individuals out of a population
- 5. population growth / A condition in which a population neither grows nor declines, because the number of births in a year equals the number of deaths.
- 7. competition / existing or occurring between different species.
- 10. / the movement of individuals into an area
- 12. independent factor / affect all populations in similar ways, regardless of the population size
- 13. transition / a dramatic change in birth and death rates
- 14. / scientific study of human population
- 16. density / the number of individuals per unit area
