Very few such "pure" predator-prey interactions have been observed in nature, but there is a classical set of data on a pair of interacting populations that come close: the Canadian lynx. His primary example of a predator-prey system comprised a plant population and an herbivorous animal dependent on that plant for food.
The relationship between body sizes of predators and their prey has been another productive area of research. These in- vestigations reveal the overall prey-size range of a predator and possibly the optimum prey-size range. Examples of this information by predator types are: amphibians (Fraser 1976), reptiles (Schoe-.
A predator-prey relationship is between two animal species —one kills and eats the other.
