Why don't ants get lost?

Ants,

I believe everyone is familiar with it.

Then who can really understand ants? Ants. Why?

Won't you get lost?

With this question, I consulted some books. According to this book, ants start from their nests and arrive at their destinations.

After landing, you will leave some smells along the way and return to the ant nest. Touch each other with tentacles and tell others.

ant Scientists have done an experiment on this problem. Scientists first discovered an ant,

Wipe the place where he reached his destination along the way. When the ant came back, it was wiped out.

The smell suddenly stopped. Looking for something while walking in circles. So that ants can get through

The sense of smell tells the direction.

To confirm this conclusion,

I did an experiment.

I prepared one about ten centimeters first.

Small branches, put a bait-small candy at one end of the branches. I put this device in.

Near an ant nest. After a while, an ant came out to explore the road. After I led him to the stick,

He came to the candy store as if he were smelling it. I take this opportunity to break this stick.

Partially cut off a stick of one centimeter. When the ant returns, it turns left where it was cut off.

Turn right, but you can't find your way home.

After a while, I repeated the above experiment, ant.

Still haven't found the way home. Through these two experiments, I finally know why ants are not fascinated.

The secret of the road.

It turns out that ants can tell the direction by smell.

Know the secret of ants

Later, I thought: Can you make an ant alarm? When the ant walks to the alarm.

Recently, alarms can "smell" ants and then chirp to let us know about them.

The ants ran into the cupboard or somewhere else.
