the overall population of a species decreased. what could have occurred to make this happen?\no the immigration rate increased, while the death rate decreased.\no the birth rate decreased, while the death rate increased.\no the carrying capacity increased, while the immigration increased.\no the emigration increased, while the birth rate increased.

Answer

Brief Explanations:

Population size is affected by birth rate, death rate, immigration, and emigration. A decrease in birth rate and an increase in death rate would lead to a reduction in population. An increase in immigration while decrease in death rate would likely increase population. Increase in carrying - capacity and immigration would also tend to increase population. Increase in emigration and birth rate could have mixed effects but not necessarily a decrease.

Answer:

The birth rate decreased, while the death rate increased.
