Question

Which segments of the earthworm contain the stomach?

(a) 9^th to 14^th

(b) 23^rd to 25^th

(c) 16^th to 18^th

(d) 5^th to 8^th

I got this question in homework.

Query is from Animals Structural Organisations in section Structural Organisations in Animals of Biology – Class 11

Answer 1

Correct choice is (a) 9^th to 14^th

For explanation I would say: The stomach of the earthworm extends from the 9^th to 14^th segments. It is present after the gizzard, where the ingested food is mechanically grinded before being passed through to the stomach.
