If you observe carefully, you will find that when ants walk, they always form a long line. Do ants queue up to listen to the teacher and must abide by discipline? Of course not.
Because when ants walk, their bodies will emit a special smell, which only ants can smell. When the ants in front walk home, the ants in the back rely on this smell to keep up, one by one, looking like a queue. Ants walk in line, actually in order not to get lost.
Usually we often see black ants. In fact, there are red, yellow, purple and blue ants! Ants live a big family life. Each family member has a clear division of labor. The queen ant is responsible for giving birth to children, the soldier ant is responsible for defending the ant nest, and the rest of the work is done by the worker ant.
