Carrying capacity.
Exponential growth.
Birth rate.
Death rate.
Logistic growth.
Logistic growth involves:
Population growth reaching carrying capacity and then speeding up.
A population crash.
Population size decreasing to zero.
Population growth slowing down as the population approaches carrying capacity.
Population growth continuing forever.
In exponential growth:
Population growth slows as the population gets close to its carrying capacity.
Population size grows more and more slowly as the population gets bigger.
Population size stays constant.
Population size grows faster and faster as the population gets bigger.
None of these are correct.
Which of the following would NOT cause population size to decrease?
