What two factors primarily determine a population’s growth rate?
Birth rate and death rate
Which survivorship curve represents species with a constant death rate
throughout their life?
Type II
What type of population dispersion occurs when individuals are spread
unpredictably?
Random dispersion
What term describes individuals leaving a population?
Emigration
What type of factor includes natural disasters?
Density independent
What type of factor includes competition and predation?
Density dependent
What type of dispersion pattern is often seen in territorial animals?
Uniform
What type of growth shows a population reaching carrying capacity?
Logistic growth
What type of population growth occurs when resources are unlimited?
Exponential growth
What term describes the movement of individuals into a population from
another area?
Immigration
What term describes the number of births in a population over a specific
period?
Birth rate
Which survivorship curve represents species with high mortality rates for
young individuals?
Type III
What factors affect population size based on the population’s density?
Density dependent factors
What type of growth shows a population increasing rapidly and then leveling
off?
Logistic growth
What type of growth occurs when a population grows without any limits?
Exponential growth
What type of factor affects population size regardless of its density?
Density independent factor

Exponential growth
What is the most common type of population dispersion in nature?
Clumped
Which survivorship curve represents species with high survival rates in early
and middle life?
Type I
What term describes the maximum population size an environment can
support?
Carrying capacity
