Plants survive in land by the water
A slug is a mollusk, it lives on land and eats plants. A leech is an annelid (segmented worm) lives in fresh or salt water depending on the type and sucks blood.
When salt is put on a leech, it causes the leech to lose water through osmosis, leading to dehydration. The salt disrupts the leech's physiological balance, causing distress and potentially death. This reaction occurs because leeches rely on their moist environment to survive, and salt creates an inhospitable condition for them. Consequently, applying salt is considered a harmful and inhumane treatment for these creatures.
