However, it is not enough to attract insects only through these two points. In order to ensure that insects will obey themselves, flowers and insects maintain a sustainable and win-win cooperative relationship. Flowers will be grateful that insects can find their other half. They will give sweet nectar to their hands. This substance is especially important for the growth of insects, especially larvae. Scarabs, butterflies and flies are heroic pollinators, but unfortunately, they spend most of their adult life mating, laying eggs and eventually facing death. Therefore, for insect-borne plants, these insects are not the best choice for pollination. Bees, on the other hand, are loyal allies of insect matchmakers, because on the one hand they have to take care of their offspring, and on the other hand they have to use flowers to brew their own food-honey. Bees will consume some nectar and pollen, but at the same time, they will also assume Cupid's responsibility and rush for the reproduction of thousands of plants.

If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.
