which is the largest digestive organ in the earthworm - how does its size make it well suited for its function?
Compare the sizes of the earthworms digestive organs?
There is a good picture of Earhtworm anatomy at the link below. You will see intestine and crop gizzard . Those are key structures in digestion.

it is the intestine. I did this lab in school. =]
The largest digestive organ in the earthworm is the gizzard. The intestine is made up of serveral organs such as the crop and the gizzard. But the biggest is the gizzard. Or so my biology teacher says.
