Question

What type of food chain exhibits the following way of transfer of energy in an ecology? Dead organism → Fungi → Bacteria

  1. A. Producer food chain
  2. B. Parasitic food chain
  3. C. Saprophytic food chain (Correct answer)
  4. D. Predator food chain

Correct Answer

Option C — Saprophytic food chain

Detailed Solution & Explanation

The food chain "Dead organism -> Fungi -> Bacteria" represents the Saprophytic (Detritus) food chain. Saprophytes are organisms (mainly fungi and bacteria) that obtain their nutrition by decomposing dead organic matter (detritus). Unlike the producer food chain (starting with green plants) or predator food chain (involving living prey), the saprophytic chain begins with dead organisms. This process of decomposition is essential for recycling nutrients back into the ecosystem. Parasitic food chains involve parasites living on a host.
