(ii) Organisms at each trophic level depend on those at the lower trophic level for their energy demands. (iii) Food chains are sustained by producers and decomposers. (iv) In a food chain, some organism like sparrow operates at one trophic level only. Select an option which shows CORRECT stat

Options

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

Correct answer

C. (ii) and (iii)

Step-by-step solution

The energy gain in an organism at each trophic level is utilized in all metabolic activities and also lost as heat to the surrounding. Thus, lower amount of energy is transferred to succeeding trophic level in a food chain. Organisms at each trophic level depend on those at the lower trophic level for their energy demands. The dead and decaying organic content are broken down to inorganic substances by the process called decomposition. It is brought about by decomposers. Producers and decomposers help in maintainin
