When I first came into contact with aliens, it was clear that establishing communication with them would be extremely difficult. Because we are entirely different from them in terms of body structure, and it is inevitable that some of their sounds are unutterable by human articulators. Other sounds are indistinguishable to the human ear. In this case, we had to use a sound spectrometer to understand what the aliens were saying. When I wanted to introduce an existing system or technology of Earth /human culture to aliens, the first thing that came to my mind was the Food chain. In an ecosystem, various organisms must feed on other organisms to maintain their life activities. Of course, this is not the way to communicate with aliens, so we used microphones, sound spectrometers, portable computers, speakers, and the pictures I prepared for aliens to explain the food chain.
In the photo, I used a very abstract method to show the structure and structure of an essential food chain. First, I will represent two animals by two sounds on the spectrogram and point out the corresponding positions in the picture. And then explain to them that one of the relationships of the food chain is that the eagles eat the bunnies at the top of the food chain. Then play the second paragraph of the spectrogram, which describes the rabbit’s sound as the same as the previous one, and you can see that the rabbit is in this food chain again. When the third spectrogram goes on, three new sounds represent three of the animals in another food chain. This time it’s birds eat snails and bugs, and snails and bugs eat grass and create a cycle. This feeding relationship is the transfer of solar energy from one organism to another, the way material energy flows and transforms through the food chain.
The number of organisms at different stages of the food chain is relatively constant to maintain a natural balance. According to their role in the movement of energy and matter, they can be divided into three fundamental ecosystems: producer, consumer, and decomposer. Popularly speaking, it is a series of eating and being eaten relations between various organisms that closely link one creature to another. The sequence of food nutrition relations between such organisms is like a chain called the food chain in ecology. The ultimate consumer is man, who not only eats meat at all levels but also eats plants. As a result, the boundaries between nutrient levels are not clear. A complex food web is an essential condition for maintaining the stability of an ecosystem. It is generally believed that the more complex the food web, the stronger the ability of the ecosystem to resist external disturbance, and the simpler the food web, the more likely the ecosystem is to fluctuate and destroy—many other important aspects of the food chain, such as energy flow and material circulation between organisms. If the food chain is deliberately destroyed, the consequences will be unimaginable!
