Read the following statements and select the correct statements. (i) DFC begins with dead inorganic matter. (ii) DFC is the major conduit for energy flow in a terrestrial ecosystem (ii) GFC of aquatic ecosystem is longer than a terrestrial ecosystem. (iv) DFC and GFC are completely separate chains.

Options

  1. A(i) and (ii)
  2. B(ii) and (iii)
  3. C(iii) and (iv)
  4. D(i) and (v)

Correct answer

B. (ii) and (iii)

Step-by-step solution

DFC is longer than GFC in terrestrial ecosystem while GFC is longer than DFC in aquatic ecosystem. Detritus is more in terrestrial ecosystem and less in aquatic ecosystem.
