Ecology - Negative Interaction - PREDATION (KMB)

Predation describes the interaction between a predator and prey species where the predator feeds on the prey. Predator-prey population dynamics are connected, as predators killing and eating prey affects prey death rates and predator birth rates. When prey numbers increase, predator numbers also increase, until prey numbers decline from over-predation and then predator numbers fall as well. Both predators and prey have evolved various tactics and responses to help ensure their survival in the predator-prey relationship.
