Answer» CORRECT option is (b) Grinding soil particles and leaves To elaborate: The gizzard has the PRINCIPAL role of grinding soil particles and decaying leaves. It does not secrete digestive enzymes nor does it PLAY a role in water absorption. It is not a RESPIRATORY structure and only helps in the mechanical breakdown of FOOD.
