Final answer:
Years of little rain in the Blue Ridge Mountains would likely cause decreased agricultural productivity due to limited soil moisture and increased drought stress on ecosystems in Georgia.
Step-by-step explanation:
If there are years of little rain in the Blue Ridge Mountains, it would likely lead to decreased agricultural productivity in Georgia. With a reduced amount of rainfall, the soil moisture necessary for crops to grow would be limited, which could result in reduced crop yields. The lack of water availability can also place stress on forests where trees have matured over decades, creating drought-stress conditions. This could influence trees to have higher stomatal density, a plant's natural response to increase water uptake. However, during a drought, this adaptation may not be sufficient, leading to further stress on forest ecosystems. Furthermore, decreased water levels can affect the reliability of groundwater sources and increase the salinity and nutrient-poor conditions of soils, both of which are detrimental to both agriculture and natural vegetation growth.
