In a terrestrial ecosystem, what is the food chain that carries a larger fraction of energy?

Options

  1. AGrazing food chain
  2. BDetritus food chain
  3. CPhotosynthetic food chain
  4. DOmnivores food chain

Correct answer

B. Detritus food chain

Step-by-step solution

In an aquatic ecosystem, 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 . Detritus food chain may be connected with the grazing food chain at some levels: some of the organisms of DFC are prey to the GFC animals, and in a natural ecosystem, some animals like cockroaches, crows, etc., are omnivores. These natural interconnection of food chains make it a food web. How would you classify
