Answer:

Garbage In, Garbage Out

Undigested material like soil passes through the worm's long intestine to be excreted as castings. Castings, also called worm manure, have great value to farmers and gardeners for soil enrichment.

Posterior compartment muscles of the thigh are the hamstring muscles, which include semimembranosus, semitendinosus, and biceps femoris. Medial compartment muscles are pectineus, adductor magnus, adductor longus and adductor brevis, and also gracilis.
