Do ants have ears? What does it use to determine direction?

Ants don't have ears, and not only that, but they don't have good eyesight, so to speak, they're blind, and their sensory organs are their antennae, and they communicate with their antennae, and they collect information. Scientists have never figured out how ants determine distance, and German scientists have done an experiment to do so. They placed food 10 meters away from the ant burrow, then grabbed the ants and divided them into 3 groups, one of which saw that the legs were 1 mm shorter, the other group had legs that were 1 mm longer by a pillar, and the third group had no longer changed legs.

The results showed that the ants who had artificially changed the length of their legs miscalculated the location of their homes. The long-legged ants only began to look for their home after walking an additional 5 meters (i.e., 15 meters more); Short-legged ants, on the other hand, start looking for a home after only 5 meters. This finding shows that the ants relied on the calculation of the number of steps to estimate the distance.

So can ants get lost? Ants often come out in search of food, and sometimes with luck, they find it right away; Sometimes they are unlucky, they haven't found it after walking for a long time, and when they want to go back, do they still recognize it for most of the day's journey? Naughty children often erase a section of the road that the ants have just climbed with their hands, and then find that when the ants want to find the original road, they encounter the erased section, and they become directionless.

It is true that ants sometimes leave a smell where they crawl, but there are also ants that do not leave a smell and remember the smell of natural gas along the way, and then find their way home. In addition, ants are also very sensitive to vision, and can use the scenery of land and sky to recognize directions. Someone once used a cylindrical tool to cover a group of ants that were about to return to the nest, so that they could only see the sky, and as a result, they were still able to follow the correct route.

Later, they used a large board to block the ants horizontally above them and lowered them as low as possible so that they could not see the sky and the surrounding scenery, and they began to lose their orientation and crawl indiscriminately. It can be seen that not only the surrounding scenery, the position of the sun, and the sunlight reflected in the blue sky can help the ants find their way.

There are no ears and the direction is judged by the antennae.

Rely on the antennae to identify the direction of the odor**.

Ants, like other insects, rely on their antennae to distinguish smells, and the first segment of the antennae is swollen and knee-shaped, making them very flexible. Because the antennae are a pair, they can not only distinguish the intensity of the smell, but also distinguish the direction and distance of the smell**, and the adults exchange food with each other, and learn about each other's health and nutritional status through their smells, and the food found by each other.

At the same time, it can also distinguish the group that the other party belongs to that kind of task, such as digging holes and building nests, or collecting food. In general, older worker ants are sent out of the nest to work.

The antennae are important sensory organs of insects, mainly playing the role of smell and touch, and some also have auditory functions, which can help insects to communicate, find the opposite sex, find food and choose spawning sites.

Insects are always swinging their antennae from side to side, as if two antennas or radars are always receiving radio waves and tracking targets. Because there are many sensory and olfactory organs on the antennae, which are connected to many sensory nerve endings in the antennal fossa, and directly connected to the central nervous system, they are very sensitive, and can not only feel objects, feel airflow, but also smell various odors, even from a distance.

Ants have the ability to discern directions. Ants rely on their antennae to identify odors and identify their ** direction. Ants rely on their antennae to distinguish smells, and the first segment of the antennae is swollen and knee-shaped, making it very flexible.

Since the antennae are a pair, it is possible to distinguish both the intensity of the odor and the directional distance of the odor**.

Ant is a kind of insect, also known as ant, Xuanju, kun mayfly, mayfly ant, belonging to the phylum Arthropod, Insecta, Hymenoptera, Ant family. There are many species of ants, there are more than 11,700 species known in the world, there are 21 subfamilies and 283 genera, and there are more than 600 species of ants that have been identified in China. Ants are also famous architects in the animal world.

They use their jaws to dig holes in the ground and build their nests by carrying sand one by one. The "chamber" of the anthill will remain in its original form unless the soil is severely dried out. Ant research expert Walter Chilgel models an anthill.

He poured liquid metal, paraffin, or orthodontic plaster into the colony of the invading red fire ants, solidified it, and then dug it out.

Ants mainly rely on the sense of smell to identify the route, relying on sunlight to identify the direction, the ant's antennae are very smart, because the ant's antennae have two functions: one is the tactile effect, through the antennae contact with the outside world, you can detect the outline, shape and hardness of the object in front, as well as the terrain fluctuations of the road ahead, and the other is the light sensing function, which can distinguish the direction according to the intensity of the sunlight.

Ants mainly rely on the sense of smell to identify the route, rely on the sunlight to identify the direction, the ant's antennae are more agile than the blind man's bamboo pole, because the ant's antennae have two functions: one is the sense of touch, through the antennae contact with the outside world, you can detect the outline, shape and hardness of the object in front, as well as the terrain ups and downs of the road ahead, and the other is the photosensitive function, which can distinguish the direction according to the intensity of sunlight.

Ants have two antennae, and they can rely on their antennae to identify directions.

How many ways do ants identify their direction? What are the types?

There are three ways for ants1 Suppose an ant uses its antennae to find its way: select an ant that is about to return to the nest, pick it up and remove its antennae with tweezers, and then put it back in place to see if it can still follow the team back to the nest. 2 Suppose the ant uses its surroundings to find its way:

While a group of ants are on their way back to the nest, use a simple screen to enclose them, and then use a flat plate to place it very low above the returning ants so that they cannot see the sky and the surrounding scenery. Under such conditions, if the ants can still return the same way, it means that the ants do not necessarily rely on the surrounding scenery to find their way. 3 Suppose the ants leave a scent on the path they have climbed on, and use the smell to identify the road when they return:

On the pavement where the ants crawled, use your finger to cross a line, disrupting the continuous scent. If the ants can still go back the way they came, it means that the ants are not using the smell left by themselves to find their way; Conversely, if the ants are confused for a short period of time, it means that the ants may be using smell to discern directions.

Ants don't have ears.

Ants don't have ears, and not only that, but they don't have good eyesight, so to speak, they're blind, and their sensory organs are their antennae, and they communicate with their antennae, and they collect information. Ants sometimes leave a smell where they crawl, but there are also ants that don't leave a smell and remember the smell of gas along the way and find their way home. Ants have no sense of hearing, but they have a keen sense of smell, and they rely on their sense of smell to find food and get home.

We usually use our antennae to exchange information with each other.

The role of ants:

1. Anti-inflammatory and analgesic, ants take it, which has a good anti-inflammatory, antibacterial, analgesic and analgesic effect.

2. Ants have a good effect of protecting the liver and protecting the liver. It can enhance the body's immunity, and taking ants can promote the activity of immune cells and lymphocytes in the body, which can be purified to enhance the body's immunity.

3. Ants have a very good effect of tonifying the kidney and strengthening yang. It has a conditioning effect on kidney deficiency. In addition, ants have a good effect of invigorating blood circulation and removing blood stasis, delaying aging, and beautifying the skin.

Therefore, in clinical application, ants have a good effect, and can be used for bone diseases, cardiovascular and cerebrovascular diseases, as well as diseases of the immune system and so on. <>

Ants have a very keen eyesight, not only the scenery on land will be used by ants to identify the way, but also the position of the sun and the sunlight shining from the blue sky can be used by ants to identify the direction of returning to the nest. In addition, in addition to relying on their eyes, ants can also recognize their way based on smells. Some ants leave a scent on the ground they crawl on, and as long as they follow it when they return, they will not go astray.

There are also ants who do not leave any special smell on the road they crawl on, but they can memorize the smell of natural gas on the road to and from and find a home.

An ant (ant) is an insect. It belongs to the phylum Arthropoda, Insecta, Hymenoptera, and Antidae. There are many species of ants, there are more than 11,700 species known in the world, there are 21 subfamilies and 283 genera, and there are more than 600 species of ants that have been identified in China.

New species of ants that reproduce asexually have also recently been discovered. Ants live for a long time, from a few weeks to 3-10 years, and a queen for more than a decade or decades, or even more than 100 years. An ant nest can grow from 1 to 10 years in one place.
