Chapter 627

The glass ball in Qin Lan's photo is called ecosphere, which is a popular small fresh decoration before the disaster.

The method is also very simple, just find a transparent glass container, lay a layer of fine sand in it, fill about two-thirds of the water, then put in small fish and shrimp, and seal the whole container.

The ecosphere 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 the light, and the proportion of small fish, shrimp and algae should be well controlled, generally speaking, it is only such a simple thing that can maintain the ecological balance for two months, which is of great research significance.

In fact, after the ecosphere was first invented by two scientists, it has always been a very meaningful research project.

If the ecosphere is compared to a small blue star, the little red shrimp represents human beings.

So this ecosphere can lead to today's blue star. The natural ecological environment is constantly damaged. If it continues to be damaged and not improved, all life may be threatened by death.

The idea of the ecosphere just reminds us of the importance of maintaining ecological balance to life. It also reminds us of the chain relationship and the mystery of all kinds of creatures on the blue star.

At the same time, before the disaster, space research institutions are also carrying out research on the ecosphere, in order to build such a balanced ecological environment with spaceships or space stations and outer space colonies as containers to 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 used to see this kind of small ecosphere in Qingyan's bar. Do you care about it, Xin?" Qin LAN sees that Chen Xin is very concerned about ecosphere, so she asks curiously.

Although she is 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 doesn't know Chen Xin's work very well. She just knows what he is doing.

Chen Xin nodded and explained to Qin LAN: "recently, we are studying the ecosystem. This ecosphere is of great reference significance."

"Is ecosystem the ecological cycle in biology textbooks before?" Qin LAN can be admitted to the civil service and become a special police officer. Of course, she can't be a scum. She still knows what these middle school students have learned.

"It's the ecosystem. Now the natural ecosystem has collapsed, so I plan to build an artificial ecosystem. But so far, it's difficult to maintain its balance and existence. It always collapses after a few years. It's not as stable as this kind of ecosystem." The bitter smile on Chen Xin's face is not that he belittles himself, but that the real artificial ecology is not as stable as the ecosphere.

Although a simple and small ecosphere like this may not work in two or three months, if it is well controlled, an Ecosphere can last for more than two to three years, or even five to seven years for larger ones, and the longest can last for more than ten years.

This is obviously more stable than Chen Xin's ecosystem.

Of course, this is mainly because of the difference in complexity between the two. After all, the internal environment of the ecosphere is very simple, the number of species is small, and the natural variables that affect the balance are also small. It is not particularly difficult to maintain the balance.

After all, there are only algae and small fish and shrimp in it, and only light and temperature can affect its ecological balance. Controlling these two variables well is enough to ensure the ecological balance in the ecosphere until the life of algae or small fish and shrimp is exhausted.

As for reproduction, it is impossible. The space of such an Ecosphere is very limited, which does not support the reproduction of small fish and shrimp or the increase of algae.

The replacement of a larger space can improve this.

Thinking of this, Chen Yu suddenly felt that he could try another way.

He stood up excitedly, took Qin LAN and gave her a kiss on the face, then rushed to the holographic image room.

Qin LAN looks at Chen Xinyi in a hurry. Although she is puzzled, she also feels helpless, but she still smiles and doesn't care. She continues to sort out the photos in front of her.

Chen Xin, who rushed to the hologram room, put his new ideas into an instrument built with nano molecules on a watch, and then projected them in the hologram room.

This time, Chen Xin did not use the method of adding everything at the beginning to build the ecosystem, nor did he use only plants to build the ecosystem, or even directly use the Dome City as the basic environment. Instead, he chose a kind of plant and an animal, like an Ecosphere. He only delineated a small space and put two species in.

In addition, all Chen Xin provides for this "ecosphere" is soil, light and enough water resources.

Chen Xin's plant is just the most common grass, and the animal is rabbit.

Rabbits eat grass, then excrete faeces, which are decomposed by bacteria and absorbed by grass again as nutrients to supply grass growth, thus forming a cycle. If there is no problem, it should be a stable system.

Of course, if the number of rabbits increases beyond the environmental carrying capacity, it will undoubtedly lead to the collapse of the whole ecosystem.

However, this is only a simulation experiment. Chen Xin only allowed rabbits to reproduce moderately and maintain the population size, but did not allow them to reproduce unrestricted.

After all, Chen Xin is very clear about the terrible consequences of rabbit overbreeding.

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 will be stable, and it can continue to cycle according to the program.

Chen Xin is not surprised by this result, because quite a lot of other variables are ignored. The whole cycle is just a simple simulation test, and there is no ecosystem to speak of. In addition, Chen Xin is also adjusting artificially. If this can collapse, then there is no need to play.

With this initial foundation, Chen Xin can carry out further tests.

That is to say, instead of artificially controlling the number of rabbit population, we put predators into it and control the number of rabbits by predators themselves.

Of course, with the addition of predators, the size of the "ecosphere" becomes narrower. Therefore, while investing in predators, Chen Xin also enlarges the size of the whole "ecosphere", improving the environmental carrying capacity and the upper limit of environmental carrying capacity.

As for Chen Xin's predators in the ecosphere, he chose the same common wolf.

Rabbits eat grass and wolves eat rabbits. In the end, the carcasses and excrement of wolves and rabbits will be decomposed and return to the earth to become nutrients of grass. In this way, the cycle will be formed.
