Answer 1

The correct option is A Decomposer only

In the group of worms lacking digestive system, the bacteria living in this system are decomposing (breaking down) the food consumed by the worm so as to release organic nutrients that are absorbed by the worm.

So, the correct answer is 'Decomposer only'.
