1. Population Dynamics

2. Exponential growth- means that as a population gets larger, it also grows faster.( J-shape) Exponential growth- means that as a population gets larger, it also grows faster.( J-shape) Straight line growth- a steady growth over time. Straight line growth- a steady growth over time.

4. Carrying capacity- the number of organisms of one species that an environment can support indefinitely. Carrying capacity- the number of organisms of one species that an environment can support indefinitely.

5. Density-dependent factors are things like competition, parasites, and food. Density-dependent factors are things like competition, parasites, and food. This is a type of limiting factor that is biotic. This is a type of limiting factor that is biotic. Density-independent factors- affect all populations, regardless of their density. Density-independent factors- affect all populations, regardless of their density. This is a type of limiting factor that is abiotic like storms, floods, and droughts. This is a type of limiting factor that is abiotic like storms, floods, and droughts.

8. Birth rate- the rate at which babies are born. Birth rate- the rate at which babies are born. Death rate- the rate at which people die. Death rate- the rate at which people die. If the birth rate is higher than the death rate you have a growth rate. If the birth rate is higher than the death rate you have a growth rate. If the birth rate is less than the death rate you have a population shrinkage (lower total population). If the birth rate is less than the death rate you have a population shrinkage (lower total population).

9. Age structure graph- shows what percentage of the population falls in what age range. Age structure graph- shows what percentage of the population falls in what age range.

10. Immigration= into population (I=in) Immigration= into population (I=in) Emigration = out of a population (E=Exit) Emigration = out of a population (E=Exit)
