7. moving into an area
8. The total number of individuals making up the population
11. A count of all the individuals in a population
15. occurs when different causes of death add to each other
16. A spreadsheet that provides a more accurate estimate of how populations might change over time
17. moving out of an area
18. The number of individuals a given area can support at a given time
19. when a population increases in proportion to its size

1. when you count a small portion of the population use it to estimate the entire population size
2. increases in predation result in compensatory declines in other causes of mortality.
3. limiting factors that affect a population in ways related to the populations density
4. factors that slow a populations growth or prevent it from existing in certain areas
6. describes the spacing of individuals in the population in relation to each other
9. how much a population is increasing or decreasing on a per individual basis
10. The number of individuals per unit of area
12. A simple and widely used method of Mark recapture sampling
13. The number of animals that the habitat can support
