1.Bees: (1) Circular Dance Scout bees crawl in circles on the spleen of the nest repeatedly, once to the left, once to the right, about half a minute to change a position and repeat.
It means that the nectar source and powder source are within 100 meters, and it does not indicate the direction. Worker bees fly out and hover for a while, and they are easy to find.
2) Tail Swing Scout bees on the spleen of the nest, while shaking their abdomen, around the "8" shaped dance circle. It represents both distance and direction.
Distance: Expressed in terms of the speed of the circle, fast rotation means close distance, slow rotation means long distance.
Direction: Determined using the angle of the sun. The angle formed by the straight line from the nest box (door) to the sun and the straight line from the nest box to the nectar source is called the "sun angle".
The direction of the Sun is transformed into a gravity perpendicular line on the nest, i.e. the Sun is above the gravity perpendicular line at all times. The angle of the intersection of the central axis of the dance circle and the gravity perpendicular line indicates the corresponding direction of the nectar source with the sun as the standard.
If the central axis of the dance circle coincides with the gravity perpendicular line, and the bee head proceeds upward, it indicates that the nectar source is in a straight line along the sun. The head of the bee is moving downwards, indicating that the nectar source is facing away from the sun in a straight line.
The counterclockwise direction of the central axis of the dance circle forms an angle to the gravity perpendicular, indicating that the nectar source is at the corresponding angle to the left of the sun.
The central axis of the dance circle forms an angle clockwise with the gravity perpendicular, indicating that the nectar source is at the corresponding angle towards the right of the sun.
Quantity and quality: The more vigorous the scout bee dances, the more nectar sources the better. However, if a swarm of bees dances wildly, it means that there is a possibility of relocation and escape, and prevention should be taken.
While dancing, the bees also share the nectar samples with their companions to taste, so that they can easily find the nectar source.
2.Peacock: Peacocks generally use their tail feathers to convey a visual message to their companions, sweethearts or people, and peacocks usually use the open screen to convey information.
Most of the birds carry messages through dance, such as flamingos, birds of paradise, etc.

-
Bees transmit messages through their dancing gestures.
Analysis: The bee tells its companion the distance and direction of the nectar source through dance. Belongs to behavioral information between animals.
-
Most of them are birds, such as red-crowned cranes, flamingos, birds of paradise, etc. Bees also transmit information through their dancing gestures.
-
Behavioral information: Some animals can send information such as recognition, intimidation, courtship and challenge to their companions through their various behaviors, such as when the swallow is courting, the male swallow makes a special flight posture around the female swallow in the air. When bees find honey, they "tell" other bees to collect honey with their dance movements.
Different dance movements have different meanings, such as a round dance gesture indicating that the nectar source is closer, and a tail swing dance indicating that the nectar source is farther away. Other bees use their sense of touch to sense the pace of the dance and get information about the nectar source.
-
Animal behavior is an adaptive activity that can be perceived from the outside by living organisms Animal behavior not only includes the movement of the body, but also includes the static posture, the change of body color or the display of body signs, vocalization, and the release of odor According to the way animal behavior is acquired, animal behavior can be divided into congenital behavior and acquired learning behavior According to the function of animal behavior, it can be divided into defensive behavior, foraging behavior, aggressive behavior, breeding behavior, etc
-
The environment has an impact on living things, and organisms can also affect the environment while adapting to the environment The adaptability of living organisms is universal, and organisms must adapt to the environment in order to survive, otherwise they will be eliminated by nature
Examples of adaptation of organisms to their environment:
1. The flag-shaped tree adapts to the environment of long-term blowing in a single wind direction;
2. The stems of cacti become fleshy to store a large amount of water, and the leaves become thorny to reduce water loss, which is suitable for the arid and water-deficient desert environment;
3. The thick fat layer of polar bears can play a role in heat preservation and adapt to the cold Arctic environment Organisms have an impact on the environment, such as:
1. Earthworms improve the soil;
2. The embankment of thousands of miles was destroyed in the anthill;
3. The transpiration of plants can increase air humidity, which indicates that organisms have an impact on the environment, so the answer is:
Examples of adaptation of organisms to their environment.
Examples of biological impacts on the environment.
1. The flag-shaped tree adapts to the environment of long-term blowing in a single wind direction;
Earthworms improve the soil.
2. The stems of cacti become fleshy to store a large amount of water, and the leaves become thorny to reduce water loss, which is suitable for the arid and water-deficient desert environment;
A thousand miles of embankment was destroyed in an anthill;
3. The thick fat layer of polar bears can play a role in heat preservation, and the transpiration of plants adapted to the cold Arctic environment can increase air humidity, etc., all indicate that organisms have an impact on the environment
-
1.Earthworms lead to good soil.
2.Forests purify the air.
3.Regulate the climate.
-
The leaves of the cactus turn into thorns, which are conducive to survival in the desert.
Antiquity: China was one of the first countries in the world to establish an organized transmission information system. As early as the Shang Dynasty more than 3,000 years ago, information transmission was recorded. >>>More

Passing by horse is called a post pass, which is an early organized form of communication. Located in the square of Jiayuguan railway station, the "post envoy" sculpture, it is taken from the Jiayuguan Wei and Jin mural tombs, the post envoy holds a simple paper, the post horse is four-legged in the air, and the speed is fast. In 1982, the First Congress of the All-China Philatelic Federation was used as a theme pattern for small stamps, which shows that Jiayuguan is one of the birthplaces of China's information culture. >>>More
