The shark is the predator and the fish is the prey. One example of a predator prey relationship would be a a shark and a fish. What are some examples of predator and prey relationships? The words “predator” and “prey” are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. This can lead to cyclical patterns of predator and prey abundance, where prey increase in number and then, with abundant food, predator number increases until the predators begin to suppress prey numbers and then decrease as well. It should come as no surprise that predators influence the numbers of their prey. How do predator/prey interactions influence both predators and prey? The prey species is the animal being fed on, and the predator is the animal being fed. In the predator prey relationship, one species is feeding on the other species. The predator prey relationship consists of the interactions between two species and their consequent effects on each other. What is the relationship between predator and prey data? The Lotka–Volterra equations, also known as the predator–prey equations, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The prey is the organism which the predator eats. So, after a slight lag, the predator population increases as well.Ī predator is an organism that eats another organism. As the prey population increases, there is more food for predators. This is shown by the graph in Figure below. How are predator and prey graph lines related to each other?Ī predator-prey relationship tends to keep the populations of both species in balance. Periodic increases in the prey population are quickly followed by increases in the predator population. What type of graph is often used to show predator/prey relationships?Įxponential Graph 4: Predator-Prey Graph The regulation of a population by predation takes place within a predator-prey relationship. The number of prey reduces when there are more predators. The number of predators increases when there is more prey. Predator-prey cycles The graph shows that there is almost always more prey than predators. 6 What is the relationship between predator and prey populations?.5 What are some examples of predator and prey relationships?.4 How do predator/prey interactions influence both predators and prey?. ![]() 2 How are predator and prey graph lines related to each other?.1 What does the predator prey graph show?.
