動(dòng)物幫了人類(lèi)的忙~ Hints: moisture dung the Nara Cape porcupines

Each melon is a valuable package of moisture and seeds. The plant also benefits from this plunder as its seeds may be carried for fifty kilometers in the elephant's stomach before being dropped in a pile of fertilizing dung.
But the Nara needs more than a passing trade with elephants to spread its seeds. Under the cover of darkness, the nutritious melons also pull in the locals, like Cape porcupines. Porcupines may wander up to fifteen kilometers a night in search of ripe melons. They rely on a sharp sense of smell.
