The relationship between the bee and the flower is a trade off of symbiosis, parasitism, predation
The answer is: barter
Bees and flowers form a mutual relationship based on the ecosystem, and you find that it includes many different relationships between the two living organisms. The pollen is transported from the flower by the bees to the site of fertilization by the bees. Here the relationship that calls for attention is revealed: the relationship between the bee and the flower depends on mutualism, coexistence, parasitism, and predation. But most of the time, the relationship between these two vital beings runs smoothly and is highly effective, as a way to enhance human life in general. Bees collect nectar from the flower (which is the bee's food), while the flowers provide more environmental protection and energy production. There are many other ecological relationships that characterize this relationship, including symbiosis, where bees and flowers work to defend each other and find ways to protect the ecosystem from harmful changes.
