Which statement is an example of a predator-prey relationship?

• A. Lynx prey on snowshoe hares
• B. Snowshoe hares prey on lynx
• C. Decomposers feed on dead organisms
• D. Plants photosynthesize

Answer: (D)

Predator-prey interactions are when one organism hunts and eats another, linking the survival and numbers of both species. This relationship helps regulate populations: when prey are abundant, predators can grow and thrive; as prey become scarce, predator numbers often fall, which can allow the prey population to rebound. A classic example is a predator that relies on a specific prey species: the predator hunts the prey for energy and nutrients, influencing each other's cycles over time. This dynamic is a cornerstone of how energy moves through an ecosystem and how communities structure themselves, with predators and prey often shaping where and how organisms live. Other options describe different ecological processes. Feeding on dead matter by decomposers is about nutrient recycling rather than predation, and plants converting sunlight into chemical energy is about energy capture by producers rather than interactions between consumer and prey.
