Final answer:
The amount of water recharged and removed from the Ogallala aquifer in 2000 is not specified. However, the aquifer is being depleted at a faster rate than it can naturally replenish. Future predictions suggest that the recharge rate will be lower than the pumping rate if current trends continue.
Step-by-step explanation:
In 2000, the amount of water recharged into the Ogallala aquifer cannot be determined from the information provided. However, it is known that the total amount of water withdrawals from both groundwater and surface water is increasing over time. The Ogallala aquifer is a shared finite resource that is being exploited at a faster rate than it can naturally replenish.
As for the expectations in 2050, it is difficult to predict the exact amount of water that will recharge the Ogallala aquifer or be pumped out. However, if the current trends of increasing water withdrawals and depletion of the aquifer continue, it is likely that the recharge rate will be lower than the pumping rate.
