| Research Abstract |
In a forest ecosystem, there is a food chain originated from detritus. The carbon originated from detritusis consumed by soil organisms and transferred to the aboveground ecosystem. Predators mix the materials originated from grazing and detritus food chains by predation. Carbon-14 concentration (Δ14C value) of predator indicates the “diet age” (carbon age) of the predator. It was concluded that relative contribution of the both pathways can be estimated by the Δ14C value of the predator.
