Predator - Prey Relationships The relationship between predators and their prey is an intricate and complicated relationship; covering a great area of scientific knowledge. This paper will examine the different relationships between predator and prey; focusing on the symbiotic relations between organisms‚ the wide range of defense mechanisms that are utilized by various examples of prey‚ and the influence between predators and prey concerning evolution and population structure. Symbiosis is
