Some seeds eaten by birds, and I imagine a certain amount eaten by cows and
other ruminents both domestic and wild, pass through the digestive system
without being broken down, exiting at the other end(sorry, I know it's
early) surrounded by fertilizer. Some plants have evolved seed bearing
fruit and seed structures in order to take advantage of this kind of
"transport".
