Emigration- individuals move out of the population’s range.

Population density- number of individuals per unit area. 

Exponential growth-population grows at a faster rate.

Logistic growth- population grows slowly overtime then stops.

Demography- scientific study of human populations 

Limiting factor- factor that controls the growth of a population. 

Density-independent limiting factors- affect all populations in similar ways, regardless of population size and density. 

Density-dependent limiting factors-operate strongly only when population density reaches a certain level.

Demographic transition- dramatic change from high birthrates and death rates to low birthrates and death rates.

When the birthrate and the death rate are the same, and when immigration equals emigration, population growth stops.

When this happens, moose may suffer from lack of food.

Exponential Growth

2. List at least two factors that will ultimately limit the bacteria population growth.
Amount of bacteria being produce(small birth rate) and disease that kills off bacteria

3. What do you think will happen to this bacterial colony over time?
It will decrease as soon as what they’re feeding off of decreases or dies out

4. Describe what causes logistic growth to occur.
Occurs when a population’s growth slows and then stops, following a period of exponential growth.
