From the web site:
Who pays for the donated rice?
The rice is paid for by the advertisers whose names you see on the bottom of your vocabulary screen. This is regular advertising for these companies, but it is also something more. Through their advertising at FreeRice, these companies support both learning (free vocabulary for everyone) and reducing hunger (free rice for the hungry). We commend these companies for their participation at FreeRice.
