The ternary relationship between predators, prey, and biomass refers to their interconnected roles within an ecosystem. Predators depend on prey as a food source, which in turn influences the biomass of both groups. When predator populations increase, they can reduce prey numbers, impacting overall biomass. Conversely, reduced predator populations can lead to increased prey availability, enhancing biomass. This dynamic interplay ensures energy transfer and maintains ecosystem balance, illustrating the importance of each species within their respective trophic levels.
