Which food chain is the major conduit for energy flow in an aquatic ecosystem?

Grazing Food Chain (GFC) Detritus Food Chain (DFC) Both 1 and 2 None of these

Grazing Food Chain (GFC)

In an aquatic ecosystem, the grazing food chain (GFC) is the major conduit for energy flow. As against this, in a terrestrial ecosystem, a much larger fraction of energy flows through the detritus food chain than through the GFC .
