Ecosystem Structure and Function · NCERT Biology

In an aquatic ecosystem, which food chain is the major conduit for energy flow?

  1. Detritus Food Chain (DFC)
  2. Grazing Food Chain (GFC)
  3. Parasitic Food Chain
  4. Saprophytic Food Chain
Show answer and explanation

Correct answer: Grazing Food Chain (GFC)

In aquatic ecosystems, GFC is the major channel for energy flow. In contrast, in terrestrial ecosystems, a much larger fraction of energy flows through the Detritus Food Chain than through the GFC.
