How rare is it to have a complete and complex ecosystem that is completely bred by nature?

　　 We must first make sure that a habitable planet does not mean a planet with a complete and complex ecosystem. The two are in the relationship between inclusion and inclusion.

　　 The habitable planet standard for humans and Serines is only-suitable for the existence of life, even if this life is just a single-celled bacteria.

　　 As long as this point is met, that terrestrial planet can be regarded as a habitable planet, even if it is just a satellite, this determination will remain unchanged.

　　 And such a range is a very broad category, suitable for the existence of life and the birth of life but two concepts.

Indeed, under the agitation of wind and current, matter will move, coupled with the baptism of thunder and lightning, inorganic matter can obtain the possibility of synthesizing organic matter in the natural environment, and in these organic matter, amino acids, the basic unit of carbon-based life, will also exist. .

But many habitable planets actually stop here, and they are not capable of nurturing life, or that they have not had time to nurture life. The gene is no less than a handful of sand, and the sand is blowing in the wind. In spontaneously assembled into a smart phone.

　　 is not impossible, but the probability is very small.

So it takes millions, tens of millions of years, hundreds of millions of years, and even when the universe heats up, this process cannot be completed, because naturally this chaotic system is completely random, especially when the probability of the birth of this kind of life is unknown—— The ghost knows why the lottery number is that string of numbers is the first prize, a truth.

Even if they are combined, they may dissipate. This may be caused by a breeze, or a free ion at a microscopic scale. The basic unit of life that has just been combined will be broken up again. Sometimes, a planet becomes alive. The ruin is so random.

The birth of life does not mean how complete the ecosystem of that planet is. The planetary life that has passed the stage of'rebirth from death' may develop into macroscopic life, or it may stay in the microbial stage forever. The habitable planet cannot provide them with enough pressure to survive, and the possibility of the latter is higher.

Then there are multi-cells, where multi-celled planetary life bodies will develop to a macro scale. This is an inevitable result, because they themselves have such a foundation. In the fierce competition for survival, multi-cellular organisms will eventually be in shape. Crush single-celled organisms on top.

However, multicellular organisms do not necessarily evolve beasts. It is entirely possible that an entire planet is a plant. The earth has had such a stage. Obviously, such planets cannot be regarded as complex and stable ecology by collectors. ring.

A mature and stable ecosystem includes three categories: producers, consumers, and decomposers. The more species there are, the more stable and fault-tolerant the ecosystem is. The extinction of a certain species will not arouse. A series of chain reactions, that's what it is all about.

Since the collectors stepped out of their own star systems, there have been tens of thousands of colonized stars, but none of the dozen or so habitable planets found in these star systems has a sufficiently complex and stable ecosystem, and the ecosystem is the best. It also evolved plants such as moss and lichen, and this plant is the epic creature of that planet, the absolute king before the arrival of the collectors.

　　 This is enough to show how rare a planet with a complex ecosystem is.

　　 With a low-power jet of gamma-rays, he first went to the earth-like planet reported by the same clan.

　　 docked the sub-light speed organism to the already-built gimbal creature, and first reached the surface through the rhizome connecting the gimbal and the planet's surface.

　　噗!

　　 emerged from the cocoon as a collector, and was hatched from the ground base of the Yuntai creature. Several collectors had been waiting there early.

　　 looked around at the beginning, the pedestal was placed on a grassland, and there were emerald green grass everywhere. Looking around, a green scene extending to the horizon of the sky showed a slight arc.

　　 The breeze blew across the grass, and the green grass swaying with the wind gave rise to waves of ripples, giving the impression that this is not land, but more like being in the middle of an ocean.

　　 "...Isn't it said that the ecological structure of this terrestrial planet is complicated? Why I can see nothing except some low-level plants."

　　 At the beginning of the strange question, the collectors answered.

　　 "This location has been cleared by us, so it is now. At the beginning, there were a lot of large animals, including aggressive predators."

　　 "Take me to see, I need to evaluate the value of this planet to the race, so that we can decide that this planet is not necessary to survive."

　　 "Okay, come with us."

　　Gatherers are efficiency-seeking creatures, so they don’t have any facade culture. They directly lead the first to a place.

　　 After a while, the grassland came to an end, and the gatherers entered a dense forest.

　　 They don’t walk fast, because they have to observe the surrounding environment, that is, the planet’s ecosystem. If they are just on the road, they will reach their destination within a few minutes by relying on the collector’s own mobility.

　　 "The plants are very lush, and many of them are aggressive, which is very rare."

　　Chu walked and observed his surroundings~lightnovelpub.net~ occasionally stretched out his tentacles, and picked the fruits, leaves and branches of some plants to eat.

　　 But this is not gluttony, it's just getting plant genes to better understand these organisms in front of them.

　　 "But why are there no animals? Didn't you say that the ecosystem of this planet is very complicated? If it is complicated, it should move... Huh?"

　　At the beginning, it suddenly stopped. It felt something strange in its body. Something was eaten into the inner body by it along with the fruits of these plants.

　　 The other party is an animal. This can be confirmed at first, because plants do not have such strong subjective initiative.

　　 This animal is a parasite. After eating part of its flesh and blood, it begins to lay eggs in its body, intending to use it as a living container.

　　Ordinary creatures might really have nothing to do with it, because it is inside the body, but unfortunately it encountered hard bones this time, and as a collector, I didn't eat this set at the beginning.

"Nonsence!"

　　 A simple operation of the organic matter in the body, the object wrapped in a mass of concentrated hydrochloric acid solution was spit out, and along with the eggs, the area with a radius of two decimeters was corroded by the spit out hydrochloric acid.

　　 The alien species, the collector, fully demonstrated its danger to this planet.

　　 "Surprise, right? A cunning animal like this, I haven't seen it since the expansion of its population for so long." The collector who led the way asked.

　　 "It's really unexpected, is there any more? Isn't it just that?"

　　The life field at the beginning of life showed interest in mood swings.

　　 "There are many more types, this is just one of many."
