Question

Gizzard in an earthworm serves for

• A. Secreting slime
• B. Absorbing digested food
• C. Excreting
• D. Crushing food

Answer 1

Answer: (D)

Crushing food

In the 8${}^{th}$ segment, the oesophagus dilates and modifies into a large, muscular oval shaped gizzard occupying 8${}^{th}$ and 9${}^{th}$ segments. The gizzard is made of circular muscles and is internally lined by a cuticle. There are chitinous teeth. It acts as a grinder which crushes the food material. After the gizzard, the food is pushed to the intestine where it is finally broken down into simpler compounds.

Thus, the correct answer is option D.
