Question

Red worms that are used in the process of vermicomposting do not have any teeth. Name the structure that helps them in grinding their food.

Answer 1

They have a structure called ‘gizzard’, which helps them in grinding their food. Powdered egg shells or sea shells could be mixed with the wastes. This would help red worms in grinding their food. A red worm can eat food equal to its own weight, in a day.
