A toilet manufactured before 1980 might use 5 to 8 gallons per flush (gpf), which means that each of the home's residents might be flushing 48 gallons of water down the drain daily. By contrast, a toilet built to 1992 standards uses 1.6 gpf, and the average flusher uses about 9.1 gallons of water daily.

A carrot is an example of a dicot root. Diagram illustrating the tissue layers and their organization within monocot and dicot roots.
