UK's Gizmodo has a time-lapse video from the program The Elephant: Life after Death, showing how in just a few days "six million calories worth of fat, meat and guts" get consumed by leopards, hyenas and vultures. As the site so eloquently explains (and warns):
This is a time lapse of what happens when you leave a dead elephant on the savannah. Yes, it's like the Lion King, but really gross. Don't play it if you don't want to see leopards, hyenas and flies putting all those proteins and carbohydrates back into the ecosystem.
