Each vaccinated child stops the transmission of the disease. therefore, as long as 90 percent of the people in a community are immunized, no one dies of the disease.

Hi there!
As resources in a population become less available, the population:
C. Reaches carrying capacity
When resources in a population become less available, the population will not be able to continue growing even more because there would be enough resources, and so, it has reached its carrying capacity.
When the exponential phase of a logistic growth curve of a population ceases:
C. Population growth begins to slow down.
The population will continue to grow but will do so at a slower and steadier rate.
I hope that helps! :)
