the overall population of a species decreased. what could have occurred to make this happen?\nthe immigration rate increased, while the death rate decreased.\nthe birth rate decreased, while the death rate increased.\nthe carrying capacity increased, while the immigration increased.\nthe 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 death - rate decreases may not necessarily decrease population. An increase in carrying capacity and immigration would likely increase population. An increase in emigration and birth rate may not lead to a definite population decrease.
Answer:
The birth rate decreased, while the death rate increased.
