All of the restaurants are using carefully chosen words to evoke vivid mental images of delicious food and rich desserts in order to draw the potential customer to their particular establishment. Just like the restaurants, nature has its own dining establishments. In a fashion similar to the restaurants' financial dependence upon drawing in many customers, the restaurateurs of the natural world (i.e., flowers) must also attract potential diners to sample their offerings. In the natural world, there are no neon signs or flashy words in which to market a potential meal to hungry animals. These restaurants that I am referring to are the world's flowers, and the potential guests are the host of organisms that visit flowers to obtain nectar and other valuable resources. Instead of using a written language or neon sign, they advertise their offerings just as effectively using the language of smell.
