Answer: E. The population size will drop until the numbers reach the carrying capacity.
A carrying capacity of the ecosystem is the number of individuals in the population of species a ecosystem can sustain on the basis of availability of resources (food, shelter). Conservationists established that the carrying capacity of a population of deer in an extensive geographical area is 945 which increased to 1,100. This sudden increase in the population of deer, will result in depletion of resources, hence, carrying capacity of the ecosystem cannot sustain increased members of the population. Therefore, the population size will drop until the numbers reach the carrying capacity.
