Does salt kill earth worms or feed them?

Salt is harmful to earthworms and can kill them. When salt is applied to soil, it draws moisture away from the worms' bodies, leading to dehydration. Earthworms thrive in moist environments and require a certain level of moisture to survive, so high salt concentrations can be detrimental to their health. Thus, salt does not feed earthworms but rather poses a significant threat to them.
