Is predator prey relationship an example of positive feedback loop?

No, a predator-prey relationship is not an example of a positive feedback loop; rather, it is an example of a negative feedback loop. In this relationship, an increase in prey population leads to more food for predators, resulting in an increase in predator numbers. However, as predator populations rise, the prey population may decline due to increased predation, which in turn can lead to a decrease in predator numbers when food becomes scarce. This cyclical dynamic helps maintain balance in the ecosystem.
