How do worms eat?
Worms have tiny mouths and will take extremely small bits out of things like bacteria, fungi and protozoa. They love organic matter such as plants, fruit, compost heaps of cut grass, potato peelings and decaying animals. When the food is too large for their mouths they moisten it to make it soft and suck it in. Worms of course have no teeth and the “gizzard” does all the work. The grains of sand or soil will be ingested in with the food along with moisture (much like birds and chickens) and a grinding process occurs. When the food leaves the worm’s gizzard is goes into the intestine and is dissolved and absorbed into the worm’s blood which also keeps the worms moist and strong. See the link below.
