- ii) Some hard seeds and fruits are eaten by animals. These seeds could not digest and passed out of body along with dung. Examples are mulberry and guava etc.

A German company called TXTR even came close to bringing this legend to life. Last October, they announced the launch of an e-book called Beagle, which consumers can buy for … $ 13! Many were intrigued and prepared to buy, because the price is more than pleasant.
