The Classic of Mountains and Seas, all of this kind of **, what are the names of people, plants, and animals. The most complete. There are them available online.

A: No, you can refer to the decomposition of cellulose, because there is no decomposition in the animal's body, and it can only rely on the reaction of microorganisms. If the chirality is wrong, there is no way to run the decomposition.
B may be able at the very beginning, but the efficiency of the two will inevitably overwhelm the other, because the heterochial substance, you can't absorb, it is equivalent to idling in the body, but it occupies resources, at this time, it depends on which of the two systems is more efficient, overpowering each other, or even exterminating the other.
Their ecosystem cannot be said to be completely independent, but should be a competitive interaction. Because the ecological circulation system is inevitably based on achiral small molecules, that is to say, the basic substances they occupy are the same, although they do not seem to be common to each other, but as mentioned in B, the higher the efficiency, the greater your share, and finally form an overwhelming advantage, by crowding out this form of interaction, to complete the evolution of life.

a.Of course, if the organism has requirements for it, it will continue to evolve, and the survival of the fittest can digest each other.
b.Living organisms have some existential relationships, such as symbiosis, mutualism, parasitism, etc., which should develop quickly after establishing a "a" relationship.
c.Ecosystems are inherently hodgepodge, and no absolutely independent ecosystems have been found at present, only under certain conditions are relatively independent.

This is because astrobiology has received strong support, but since some extraterrestrial organisms have not been discovered, astrobiology is often just empty talk。And once extraterrestrial creatures are discovered, it will bring great misfortune and loss to human beings, because the ability of extraterrestrial creatures may far exceed that of humans, which also leads to a very embarrassing situation in astrobiology now. On the one hand, I hope to discover some alien creatures as soon as possible, but on the other hand, I am afraid that these alien creatures will bring great disasters to mankind.
Extraterrestrial life has always been a subject of human research, because the only higher beings we know now are humans, but everyone thinks that there must be other creatures in the universe. Human beings want to explore space all the time, but there has always been a great resistance to extraterrestrial creatures, mainly because once extraterrestrial creatures are in an aggressive attitude towards human beings, it will bring great harm to the survival and development of human beings.
So the discipline of astrobiology has always been very contradictory, because many people don't know if there are extraterrestrial creatures, but once there are extraterrestrial creatures,Whether or not it proves that extraterrestrial creatures are beneficial to human beings, so now researchers in angel biology are in a very ambivalent state of mind. Because on the one hand, they want to find extraterrestrial creatures, but on the other hand, they don't want to find space creatures.
Of course, whether there are extraterrestrial creatures or not, it mainly depends on how far the level of human development can be, once extraterrestrial creatures appearWhether humans are capable of coping, and if not, how can human beings avoid catastrophes?
-
The reason why astrobiology is the luckiest and most unfortunate discipline of the last hundred years is because the technological tools have developed very quickly, but they have not achieved much.
-
Probably because of astrobiology, his research does not help ordinary people's lives in any way, so it is an unfortunate subject.
-
Because in the past 100 years of the history of celestial bodies, there has not been enough developed science and technology to study this science, but with the development of history, people have discovered the secrets that exist in this science.
-
I think the main reason is that he does have some shortcomings, and then he gives people a very bad feeling, which is why he says that.
-
Because he came out of a difficult stage, and his development was hindered and difficult in all aspects, he said so.
-
If humans are able to carry out spacewalks and even travel in the future, it will inevitably spread all kinds of life on Earth on other planets, and may bring extraterrestrial pathogens and other creatures back to Earth.
