Question

reinforcement: populations (chap 5)
emigration distribution density dependent
demography exponential carrying capacity range
growth rate logistic immigration predator - prey

1. the physical area where a population lives: geographic
2. describes how a population size changes (positive, negative, zero):
3. the number of individuals in an area is the population
4. how individuals are spaced in an environment:
5. movement into a population:
6. movement out of a population:
7. describes a population growing under ideal conditions: growth.
8. describes a population that grows under limiting conditions: growth.
9. the number of individuals an environment can support is the
10. competition, disease and crowding are density factors.
11. a type of graph that shows changes in two populations over time:
12. the study of human populations:

Explanation:

1. The term for the physical area where a population lives is "range".
2. Growth rate describes how a population size changes (positive, negative, zero).
3. Population density is the number of individuals in an area.
4. Distribution refers to how individuals are spaced.
5. Immigration is movement into a population.
6. Emigration is movement out of a population.
7. Exponential growth occurs under ideal conditions.
8. Logistic growth occurs under limiting conditions.
9. Carrying capacity is the number of individuals an environment can support.
10. Competition, disease, and crowding are density - dependent factors.
11. A predator - prey graph shows changes in two populations over time.
12. Demography is the study of human populations.
