The glass ball that appears in Qin Lan¡¯s photo is called an ecological ball, which was a very popular and fresh decoration before the disaster.
The method is also very simple, just find a transparent glass container, put a layer of fine sand inside, fill it with about two-thirds of water, then add small fish and shrimp, and seal the entire container.
The ecological ball created in this way can maintain the ecological balance for about two months. Although it needs to be exposed to the sun every day to ensure light, and the proportion of small fish, shrimp and algae must be controlled, but in general, such a simple thing can maintain the balance. Two months of ecological balance is already of considerable research significance.
In fact, after the ecosphere was first invented by two scientists, it has always been a very meaningful research project.
If the ecological ball is compared to a small blue star, the small red shrimp represents human beings.
So this ecological ball can lead to today's Blue Star. The natural ecological environment is constantly being destroyed. If it continues to be destroyed and is not improved, all life may be threatened by death.
The idea of ??this ecological ball just reminds humans of the importance of maintaining ecological balance to life. It also reminds people of the chain relationships between various creatures on the Blue Star and the mysteries therein.
At the same time, before the disaster, aerospace research institutions were also conducting research on ecological spheres, in order to use spaceships or space stations and outer space colonies as containers to build an ecological environment that can maintain a balance and ensure the survival of human beings.
This coincides with Chen Xin¡¯s current purpose and can also provide him with a lot of reference.
"I saw this kind of small ecological ball placed by Qing Yan in her bar. Ah Xin, do you care about this?" Qin Lan asked curiously when she saw that Chen Xin was very concerned about the ecological ball.
Although they are together every day, Qin Lan's main job is to assist in the development and design of Titan. In addition, she is not the kind of person who likes to ask Chen Xin what he is doing every day, so she does not know much about Chen Xin's work, but she only knows him generally. It¡¯s just what you¡¯re doing.
Chen Xin nodded and explained to Qin Lan: "I have been studying ecosystems recently, and this ecological ball is of great reference significance."
"Is the ecosystem the ecological cycle that was taught in biology textbooks before?" Qin Lan can be admitted to the civil service and become a special police officer. Of course she cannot be a scumbag. She still understands these things that middle school students have learned.
"It's that ecosystem. Now the natural ecology has collapsed, so I plan to build an artificial ecology. But so far, it's difficult to maintain its balance and existence. It always collapses after only a few years of operation. It's not as good as this ecological ball. Stable." A bitter smile appeared on Chen Xin's face. This was not because he was belittling himself, but because the real artificial ecology was not as stable as the ecological ball.
Although a simple and small ecological ball like this may not last for two or three months, if it is well controlled, an ecological ball can actually last for more than two to three years, and even larger ones can last for five years. to seven years, and the longest one can persist for more than ten years.
This is obviously much more stable than the ecosystem built by Chen Xin and others.
Of course, this is mainly due to the difference in complexity between the two. After all, the environment inside the ecological sphere is very simple, the number of species is very small, and there are few variables that naturally affect the balance. It is not particularly difficult to maintain balance.
After all, there are only algae and small fish and shrimps in it. The only things that can affect its ecological balance are light and temperature. Controlling these two variables is enough to ensure the ecological balance in the ecological ball until the lifespan of the algae or small fish and shrimp. exhausted.
As for reproduction, it is impossible. The space of an ecological ball like this is very limited and does not support the reproduction of small fish and shrimps or the increase of algae.
And replacing it with a larger space can improve this.
Thinking of this, Chen Yu suddenly felt that he could try another method.
He stood up excitedly, hugged Qin Lan and kissed her on the face, then rushed towards the holographic imaging room in a hurry.
Qin Lan looked at Chen Xin's hurried look. Although he was a little confused and felt helpless at the same time, he still smiled, didn't care, and continued to sort out the photos in front of him.
Chen Xin, who rushed to the holographic imaging room, input his new ideas into an instrument built from nanomolecules on the watch, and then projected it in the holographic imaging room.
This time, Chen Xin did not use the method of adding everything in from the beginning to build the ecological system, nor did he only use plants to build the ecological system, or even directly use the dome city as the basic environment, but chose a Plants and animals, like making an ecological ball, only circled a small space and put two species in it.
removeIn addition, all Chen Xin provides for this "ecological ball" is soil, light, and sufficient water resources.
The plants Chen Xin put into it were just the most common and common grasses, and the animals were rabbits.
?? Rabbits eat grass and then excrete feces, which are decomposed by bacteria and reabsorbed by the grass as nutrients to supply the grass with growth. This forms a cycle. If there are no problems, this should be a system that can operate stably.
Of course, if the number of rabbits increases beyond the environmental carrying capacity, it will undoubtedly lead to the collapse of the entire ecosystem.
But this is just a simulation experiment. Chen Xin only allowed the rabbits to breed in an appropriate amount to maintain the population, but did not allow them to breed unrestrictedly.
After all, Chen Xin is very clear about the terrible consequences of excessive rabbit breeding.
Because the number of rabbits is artificially controlled, this cycle has not been broken. After the number of rabbits reaches the upper limit of the environment's carrying capacity, it stabilizes and can continue to cycle according to program calculations.
Chen Xin was not surprised by this result, because a lot of other variables were ignored, and the whole cycle was just a simple simulation test. There was no ecosystem at all. In addition, Chen Xin was also artificial. I'm making adjustments. If it crashes, there's no need to play anymore.
With this preliminary foundation, Chen Xin can carry out further tests.
That is to no longer control the rabbit population artificially, but to put predators into it, and use the predators themselves to control the rabbit population.
Of course, with the addition of predators, the size of the "ecological ball" becomes narrower, so while adding predators, Chen Xin also enlarged the size of the entire "ecological ball", which not only increased the environmental carrying capacity, but also The environmental carrying limit has been increased.
As for the predators Chen Xin put into the "ecological ball", he chose the equally common wolf.
Rabbits eat grass, wolves eat rabbits, and finally the corpses and excrement of wolves and rabbits will be decomposed and returned to the earth to become nutrients for grass, thus forming a cycle. (Remember the website address: www.hlnovel.com
