Cuisine varies greatly around the world, but the basic ingredients that sustain humans are pretty similar. We eat a lot of corn, wheat, rice and other simple crops. Read on to find out which foods top the list of most important worldwide, listed by annual production and average yield in 2008.

The red outlines the highest or loudest part of the sound. The image shows the 3 seconds of the meadowlarkâs song. We see that between 1,744 and 6,000 Hz (the frequency) is the major part of the sound whereas at 2.2 seconds into the sample it dips lower, too. Consider a spectral analysis a voice print.

If the judge where only those of the same species, then the winner would be the elephant. I would include a sound clip of the elephant, but humans cannot hear the sound they make, due to the low frequency.
