What is one of the impacts due to lower precipitation?

Lower precipitation leads to decreased soil moisture, which is crucial for plant growth. When there is less rainfall, crops may not receive the necessary water they need to thrive, resulting in poor growth and lower yields. This impact is particularly significant in agricultural regions where reliance on consistent precipitation is high. Adequate water is essential during critical growth stages, and without it, plants can become stressed or even die, leading to a reduction in the overall harvest.

The other aspects related to the other options do not accurately represent the typical consequences of lower precipitation. For instance, increased crop yields suggest a surplus of water and nutrients, which contradicts the challenges faced during periods of drought. Similarly, increased risk of flooding typically arises from excessive precipitation rather than a decrease. Enhanced forest growth also requires sufficient rainfall; thus, lower precipitation would hinder this growth rather than promote it.
