Population Ecology 8

2. Population depends on…
Population Density: # of organisms per unit area
Spatial Distribution: pattern of spacing of a population
Population Ranges: whether or not a species can expand

3. Populations are affected by …
Density-independent factors (abiotic)
Density-dependent factors (biotic)

4. Three factors affect population growth …
the number of births (birth rate)
the number of deaths (death rate)
the number of individuals that enter or leave the population (immigration vs. emigration)
**A population can grow when its birthrate is greater than its death rate.

5. Two types of population growth …
Exponential Growth: (J-shaped)
Logistic Growth: (S-shaped)
Growth stops when the population reaches carrying capacity.

6. Population growth depends on limiting factors …
A limiting factor is a factor that causes population growth to decrease.
Examples: water, food source, land, etc
