Dogs can go home accurately when they smell their own urine, but I found a strange phenomenon-ants can also go home accurately.
This is due to an accidental discovery. Several children are playing in the yard. I accidentally dropped the candy in my mouth and soon attracted a large group of ants. I found that ants come from the same road, and it is accurate. Why? I began to observe carefully. I found that ants always shake their tentacles when they come out of the hole. Is it related to tentacles? So I did an experiment to cut off the tentacles of all the ants who just came out of the hole. Those ants are crawling around like headless flies and can't find food at all. In order to verify whether ants use their antennae to tell the direction, I did the same experiment again. The results show that once ants cut off their antennae, they can't find the direction of food.
Do ants only use their tentacles to tell directions? After careful observation, I found that the ant's tail would touch the ground from time to time. I imagined that it might be that the ant's tail touched the bottom and secreted something, and the tentacles were used to sense the existence of things and sniff out the things secreted by the tail to go home.
In order to test this hypothesis, I did another experiment. When the ant helped the food back to its nest, it wrapped its tail, but it was not cut. Sure enough, the ants can't go home. I repeated the experiment several times and the result was still the same. In order to make this answer more true, I checked the information on the Internet. Sure enough, the answers written online are basically the same as mine. What the ant's tail spits out is called "trace pheromone", which can make the ants returning to the hole accurately, and the ants leaving the hole accurately find food.
I'm so glad I solved the secret of ants looking for food and going home!
