Why is death rate considered as effectors of population growth?

Death Rate is considered an effector of population growth because it directly influences the size of a population by determining how many individuals survive over a given period. A high death rate can lead to a decline in population numbers, whereas a low death rate may contribute to population increases. Additionally, when examining population dynamics, changes in death rates can indicate environmental pressures, health conditions, and the effectiveness of social policies, all of which impact overall population trends. Thus, understanding death rates is essential for predicting and managing population changes.
