what are tye possible impact on the limiting factors that determine population size of an extended period of lower thab normal rainfall

"When the period of the normal rainfall will decrease there will be subsequent decrease in the population size. Due to low water supply the food supply will also decrease, and increase the death rate. Hence, The population's resource supply will be directly affected."

Explanation:

The population's resource supply will be directly affected. The amount of water available will be less than usual, which will in turn affect the food supply of different animals. This will likely cause the birth rate to decrease and the death rate to increase, which will reduce the population size. Water is the basic need for life. If water will not be there then the existence will not also possible. Without water life in the Earth is impossible.
