    The failure of the ecological environment test did make many researchers and Chen Xin feel frustrated, but it was only a dozen failed experiments, which did not make people lose their fighting spirit.

    ??And they will always cause the entire ecosystem to collapse just by adding animals. If it is just plants, the entire ecosystem can be maintained in a relatively stable state for at least five hundred years.

    This also proves that the construction of artificial ecological systems is feasible, but compared with plants, which are relatively stable and controllable, animals are relatively more prone to changes, which can lead to imbalances in the ecological system and ultimately lead to ecological collapse.

    Chen Xin¡¯s initial idea was to add animals to this relatively stable ecosystem consisting only of plants, but previous experiments proved that this was not feasible.

    The failure of the first few experiments was largely due to the mismatch between plants and animals, which made it impossible for the two to coexist.

    In several subsequent experiments, they tried to put animals and plants into the experiment together, but the difference in reproduction speed between different species could easily lead to the collapse of the entire ecosystem.

    This is why after the failure of the seventeenth experiment, some people suggested changing their thinking.

    Because according to the original thinking, they tried all the solutions they could try. Facts have proved that they must jump out of their original thinking.

    So after the seventeenth experiment, Chen Xin gave everyone a holiday and asked everyone to take a day off, change their minds, and see if they could generate some new ideas and ideas.

    And he himself also tried to adjust his thinking and think about the problem.

    An ecosystem generally consists of four parts: the abiotic environment, producers, consumers and decomposers. In order to maintain the operation of an ecosystem, these four parts are indispensable.

    In Chen Xin¡¯s current experiments, the abiotic environment is the best guaranteed and the most stable part among the four parts.

    As for producers, they usually refer to the green plant parts. Although this part is not as stable as the abiotic environment, there is no need to worry too much. They can already build a stable plant ecosystem.

    But the consumer part of the entire system really stumped Chen Xin and the researchers.

    Although by definition, animals are consumers in the ecosystem from the bottom up, in fact every link in the entire food chain can be regarded as a producer and consumer.

    They consume the next level, and they themselves will be consumed by the upper level of the food chain. Eventually, the existence at the top of the food chain will be decomposed by decomposers after death, forming a closed loop of the entire material cycle and energy flow.

    So the supply and demand relationship between each species and other species is the key to maintaining the balance of the entire ecosystem.

    This is like a production line. Raw materials are input from the source, the raw materials are processed into parts in the processing workshop, and then assembled in the assembly workshop. The amount of work done in each link is calculated in advance, no more, no less.

    If there is more or less of one link, it will cause problems in the entire production line.

    Too much will cause more and more things to pile up in a certain link, while too little will lead to a reduction in the final product of the production line.

    It¡¯s just that the production line in the factory can be adjusted very directly, but the ecological environment is obviously not so easy to control and adjust.

    Although humans can indeed play a regulating role in the ecological environment of the dome city, allowing the entire ecological environment to last longer, but if the ecological system itself has problems, then even if there is external interference, it will only function for a while longer.  It will eventually collapse.

    And if there are problems in some aspects, even external intervention will be difficult to save the entire ecosystem.

    This can be clearly seen in the 16th and 17th experiments. The massive reproduction of insects caused a terrible scene like a locust plague. Even if human intervention occurs, the end result will be that the entire ecological system must be rebuilt.

    Of course, that will lead to such a result because without external intervention, the entire ecological system has been completely out of balance.

    If there is a monitoring system that can monitor the entire ecological environment at all times, and deal with problems and variables in a timely manner when problems are discovered, to a certain extent, it can indeed maintain the operation of the entire ecological system.

    As long as there is no problem that causes the entire ecosystem to collapse in an instant, this can actually keep the entire ecosystem running smoothly for a long time.

    But the dome city can do this, but if you want to restore the entire Blue Star's ecology later, this will undoubtedly not work

    After all, humans currently do not have the power to monitor the entire Blue Star ecology and make timely adjustments to possible problems.

    Therefore, Chen Xin must find a way for the entire ecosystem to operate smoothly without external interference.

    But how easy is this?

    After giving up thinking about this problem, Chen Xin decided to give his brain a rest and change his mind to see if he could get new inspiration.

    So he left the scientific research center and returned to his home.

    Back home, Chen Xin noticed that Qin Lan was sitting on the sofa sorting something, so he walked over curiously and asked her, "What are you looking at?"

    "Some photos. Among the things Qing Yan brought back before, there are many old photos, so I'll sort them out." Qin Lan answered Chen Xin's question and looked up at him: "Why are you back so early today?  ?¡±

    "I encountered some obstacles at work, and the experiment failed, so I just gave everyone a day off to let everyone take a rest and change their minds." Chen Xin said this, sat down next to Qin Lan, and picked up the things she had organized  The good photo album was flipped through.

    Most of the photos above are photos of them having fun in Mo Qingyan¡¯s bar, and some were taken when everyone went outdoors together.

    Chen Xin looked at these photos and recalled those happy times in the past, and couldn't help but feel relaxed.

    But when Chen Xin was flipping through these photos, he suddenly noticed something different about one of them.

    The photo was taken of Qin Lan, but she was completely different from Chen Xin's impression that she was always wearing training uniforms at that time. Instead, she rarely wore a plain white dress, and she looked very quiet sitting in a  In front of the table, there was a glass ball covered with stones, like a fish tank, with small fish and algae in front of her.

    What really caught Chen Xin's attention was the glass ball. He asked Qin Lan curiously: "Alan, when did you take this photo? And what is this ball? If there is no opening, there will be no shortage of fish inside.  Are you going to die from suffocation on oxygen?" (Remember the website address: www.hlnovel.com
