What describes a predator-prey relationship?

Explanation:
A predator-prey relationship is defined by a situation where one species hunts and consumes another species for food. In this dynamic, the predator is the organism that initiates the hunt, while the prey is the organism that is being pursued and eaten. This relationship plays a crucial role in balancing ecosystems, regulating population sizes, and promoting natural selection. In predator-prey interactions, the predator's population may increase when there is a plentiful food supply provided by the prey, whereas an overabundance of predators can lead to a decline in the prey population. This dynamic can ultimately influence the health and stability of the broader ecosystem. Other options do not accurately represent the distinctive nature of a predator-prey relationship. A partnership suggests a mutual benefit, which is not the case here, as one organism is harmed while the other benefits. Symbiosis refers to a close relationship between species that typically benefits both, unlike predator-prey, where the predator benefits at the prey's expense. Lastly, a competitive struggle refers to competition for resources rather than a direct hunt, distinguishing it from the predator-prey dynamic.
