Population density
A population that is stable...
swings wildly between highs and lows.
stays within a limited range.
collapses and reaches a population size of 0.
grows at a rapid rate and then crashes when it exceeds carrying capacity.
A population that is unstable...
stays within a limited range.
swings wildly between highs and lows.
stays around carrying capacity.
has about the number of organisms that the ecosystem can support.
What is exponential growth?
A pattern where population growth increases rapidly.
Population moving out of an environment.
Population growth slows/stops after a period of great growth.
A limiting factor.
What is it called when individuals move INTO its range from elsewhere?
Growth rate
