Chapter 482: Chapter 483 The Complex Planet of the Ecosphere
How rare is it to have a complete and complex ecosystem that is completely dependent on nature?
First of all, it should be confirmed that a habitable planet is not equal to a planet with a complete and complex ecosystem. The relationship between inclusion and inclusion is between the two.
The standard of a habitable planet for humans and Selin is just - suitable for the existence of life, even if this life is just a single-celled bacterium.
As long as this is met, the terrestrial planet can be identified as a habitable planet. Even if it is only a satellite, this determination will not change.
And such a range is a very broad category, which is suitable for the survival of life and the birth of life.
Indeed, under the stirring of wind, matter will move, and coupled with the baptism of thunder and lightning, inorganic matter can obtain the possibility of synthesizing organic matter in a natural environment, and among these organic matter, amino acids, the basic unit of carbon-based life, will also exist.
But many habitable planets actually stop here. They don't have the ability to give birth to life, or they don't have time to give birth to life. They make a pile of miscellaneous substances into genes, which are no less than raising a handful of sand, which spontaneously assembles into a smartphone in the wind.
It's not impossible, but the probability is pitifully small.
Therefore, it takes millions, tens of millions, hundreds of millions of years, and even when the universe is silent, this process cannot be completed, because the chaotic system of nature is completely random, especially when the probability of birth of life is unknown - it is a reason why the lottery number is the string of numbers is the jackpot.
Even if it is combined, it may dissipate, which may be the water flow fluctuation caused by a breeze, or a free ion on a microscopic scale, so that the basic unit of life that has just been combined is broken up again. Sometimes, the interruption of the vitality of a planet is so casual.
The birth of life does not mean that the ecosystem of that planet is so complete. Planetary life that has passed the 'reincarnation from the dead' stage may develop into macro life, or it may always stay in the microbial stage. If the habitable planet that nurtures them cannot provide them with enough pressure to survive, The possibility will be higher.
Then there is multi-cells. The development of multi-cellular surface life on a multi-cellular planet has developed to a macro scale, which is an inevitable result, because they themselves have such a foundation. In the fierce survival competition, multicellular organisms will eventually crush single-cell organisms in size.
However, multicellular organisms do not necessarily evolve into animals. It is completely possible that a whole planet is a plant. The earth once had such a stage, and such planets are obviously not regarded as complex and stable ecosystems by collectors.
A mature and stable ecosystem includes three categories: producers, consumers and decomposers. The more species they have, the more stable the ecosystem is and the fault-tolerant it is. The extinction of a species will not provoke a series of chain reactions. That's the same thing.
Since the collectors stepped out of their own star system, there have been tens of thousands of colonized stars, but in these star systems, none of the more than a dozen habitable planets found has a complex and stable enough ecosystem. The best in the ecosystem has evolved such plants such as moss lichen, and this plant is the history of that planet. Poetical creatures, the absolute king before the collectors arrive.
This is enough to show how rare a planet with a complex ecosystem is.
With low power, he sprayed the gamma ray stream and went to the terrestrial planet reported by the same race for the first time.
The subluminal speed organisms are parked at the built cloud platform organisms, and the rhizome connected to the surface of the planet's surface is first reached through the rhizome of the cloud platform.
Poo!
At the beginning, he broke out of the cocoon as a collector and was hatched from the ground base of the cloud platform creature. Several collectors have been waiting there early.
At first glance, I looked around. The base was on a grassland, full of emerald green grass. Looking around, there was a green scene, extending to the horizon of the sky, showing a slight arc.
The breeze brushed the grass, and the grass swaying with the wind rippled, giving people the feeling that it was not land, but more like being in an ocean.
"...Isn't it said that the ecosystem structure of this terrestrial planet is complex? Why can't I see anything but some low-level plants?
At the beginning of the strange inquiry, the collectors answered.
"This location has been cleaned up by us, so it's like this. At first, there were a lot of large animals here, including many aggressive predators."
"Try to see. I need to evaluate the value of this planet to the community, so we can decide that there is no need for this planet to survive."
"Okay, come with us."
Collectors are creatures that pursue efficiency, and there is no facade culture. They directly lead the first place.
After a while, the grassland came to an end, and the collectors entered a dense forest.
They don't walk very fast, because they first want to observe the surrounding environment, that is, the planet's ecosystem. If they are just on the way, they will reach the destination in a few minutes with the collector's own mobility.
"The plants are very lush, and there are many aggressive plants, which is very rare."
While walking and observing the surroundings, occasionally stretches its tentacles and picks off the fruits, leaves and branches of some plants and eats them.
However, this is not greedy, but just getting the genes of plants to know more about these organisms in front of you.
"But why are there no animals? Didn't you say that the ecosystem of this planet is very complicated? If it's complicated, it should move... huh?"
At the beginning, it suddenly stopped and felt the strangeness in its body. Something was eaten into the inner body with the fruits of these plants.
The other party is an animal, which can be determined at the beginning, because plants do not have such strong subjective initiative.
This animal is a parasitic creature. After nibbling part of its flesh and blood, it begins to lay eggs in its body, intending to use it as a living container.
Ordinary creatures may really have no choice, because it is in the body. Unfortunately, this time it encountered a hard bone, and as a collector, it did not eat this set at first.
"Ah-Bah!"
After simply operating the organic matter in the body, the object wrapped in a mass of concentrated hydrochloric acid was spit out, together with eggs, and the area with a radius of two minutes was corroded by the initially spit out hydrochloric acid.
The collector, an alien species, fully shows its danger to the planet.
"Surprise, right? I haven't encountered such a cunning animal for so long. The collector leading the way asked.
"It's really unexpected. Is there anything else? Isn't it just like this?"
The initial life field shows mood swings of interest.
"There are many other types, which is just one of many."
