The formation of biodiversity, the process by which new species are constantly formed?

Biodiversity is the ecological complex formed by organisms and their environment, and the synthesis of various ecological processes related to it, including animals, plants, microorganisms and their genes, as well as the complex ecosystems formed by them and their living environment.

The definition of biodiversity includes the interaction between organisms, as well as the combination of organisms and the environment, which is a large category of the entire natural ecological environment, not just the formation of new species.

Biodiversity refers to a stable ecological complex formed by the regular combination of a variety of living organisms (animals, plants, microorganisms) within a certain range. This diversity includes the diversity of animals, plants, and microorganisms, the diversity of genetic and variation of species, and the diversity of ecosystems.

From this definition, it can be seen that it is not enough to have new species to form, but also to "form a stable ecological complex with regular combinations".

Changes in biodiversity can occur in the short term, for example, a disaster in a certain area will lead to a decrease in biodiversity, while a certain area will increase biodiversity if the environment is well protected, and there is no absolute relationship with the formation of new species.

But the formation of new species can increase biodiversity.

Biodiversity includes genetic diversity, species diversity and ecosystem diversity.

The formation of biodiversity is reflected in the continuous formation of new species.

Wrong, of course.

The formation of biodiversity is the formation of a relatively stable environment by the small increase of biological species in a certain population.

If the formation of biodiversity is the process of the continuous formation of new species, then we should not study biodiversity, it takes hundreds of years to produce a new species, and those scholars are not waiting to die there.

Biodiversity is the ecological complex formed by organisms and their environment, as well as the synthesis of various ecological processes related to it, including animals, plants, microorganisms and their genes, as well as the complex ecological origin system formed by them and their living environment.

The definition of biodiversity includes the interaction between organisms, as well as the combination of organisms and the environment, which is the general category of the entire natural ecological environment, and the forest is not only the formation of new species.

a. The content of biodiversity includes: genetic diversity, species diversity and ecosystem diversity; The formation of biodiversity is not just a process of the continuous formation of new species, a mistake;

b. Due to the change of gene frequency in the population during the evolution of organisms, the genetic material of the organism will be changed, which can be passed on to the next generation, with continuity, b correct;

c. Natural selection determines the direction of gene frequency change in the population, and the change in the gene frequency of the population is spontaneous and cerrorous;

d. Natural selection determines the direction of biological evolution, and the direction of biological variation is not directional

Biodiversity is genetic diversity, ecosystem diversity and species diversity.

The reasons for the formation of biodiversity can be summarized as "co-evolution".

--Coevolution is the continuous evolution and development of different species, between organisms and the inorganic environmentThrough a long process of co-evolution, not only a thousand species have emerged on the earth, but also a diverse variety of environments have formed.

Because the causes of genetic and species diversity are: genetic mutation, recombination, natural selection, and geographical isolation.

The question asks about the causes of the formation of ecosystem biodiversity, and "co-evolution" can be summarized as the reasons for the formation of ecosystem diversity. See the textbook for compulsory 2, the above paragraph seems to be the original sentence of the textbook.

The causes of species diversity are: genetic mutation, recombination, natural selection, geographical isolation.

Formation of biodiversity: The formation of a new species from the original species is called speciation. There are different hypotheses about the mechanism of new speciation, but genetic mutation and natural selection are two basic processes.

Geographical isolation and reproductive isolation play a key role in the speciation process. According to the area of the species, it can be roughly divided into three types: exotic, homogeneous, and neighborial.

Exotic. Multiple populations of a species live in different spatial ranges, and the genetic exchange between these populations is hindered due to geographical isolation, resulting in the accumulation of different genetic variations in specific populations and the gradual formation of their own unique gene pools, and finally reproductive isolation from the original population, forming new species.

Same-region type. Species living in the same area diverge in ecological niches due to resource constraints and fierce competition within populations. Populations occupying different ecological niches develop barriers to gene exchange, and new species are formed through reproductive isolation.

Neighborhood type. Some species have a wide range of distribution areas but poor dispersal ability, and some populations in the marginal areas of their ranges, due to differences in habitat environment, form obstacles to gene exchange, gradually establish their own unique gene pools, and form reproductive isolation, and finally form new species.

(1) Genetic diversity determines the diversity of biological species Therefore, the diversity of biological species is essentially the diversity of genes (DNA), which is the fundamental reason for determining biodiversity

2) From an evolutionary point of view, the reason for the diversity of biological traits is that diverse environments carry out natural selection of biological populations in different directions

3) From the perspective of the whole biological world, different types of communities are distributed in different ecological environments, which reflects the diversity of ecosystem levels

4) Direct value includes economic value, appreciation value, medicinal value and scientific value According to the title, the direct value of yew is explained from the perspective of biodiversity value

5) The grazing amount should be controlled between point b and c in the figure, so as to maintain the stability of the grassland ecosystem and obtain more livestock production

If the grazing amount of the grassland ecosystem is above point c in the figure for a long time, it will cause grassland degradation, desertification, and biodiversity reduction

Compared with forest ecosystems, grassland ecosystems have fewer species of animals and plants, simpler trophic structure, and less self-regulation ability

So the answer is; (1) Genetic diversity.

2) The environment conducts natural selection for biological populations.

3) Ecosystem.

4) Direct value.

5) It can not only maintain the stability of the grassland ecosystem, but also obtain high livestock yields Grassland degradation, desertification, and reduced biodiversity The trophic structure of its community is simple.

The interaction between matter, matter and the environment, leads to the formation of biodiversity.

The reasons for the formation of ecosystem diversity can be summarized as follows: ( c co-evolution).

a Genetic mutation and recombination b Natural selection c Co-evolution d Geographic isolation.

Because of environmental influences, genetic mutations evolve. Choose A

Select C, which has relevant content in the textbook.

"Co-evolution" refers to the type of evolution in which genetic evolution occurs in one species as a result of the influence of another species. For example, a plant undergoes genetic changes due to pressure exerted by herbivorous insects, which in turn leads to genetic changes in insects. Rather than several species evolving in one direction.

It includes: 1. The "shrewd predator" strategy: predators generally cannot eat all their prey, otherwise they will not be able to survive themselves.

2. "Harvest theory": predators tend to prey on species with a large number of individuals, so as to avoid the situation that one or several organisms dominate the ecosystem, and make room for the formation of other species to increase the diversity of species.

"Co-evolution" will also prevent one species from being dominant and others to the brink of extinction among species that exist in the same niche in the same area, resulting in biodiversity.

Based on the above theory, you should choose C for multiple choice questions.

No, if there is an evolutionary one. In fact, there has never been any evidence of the existence of evolution. Fossils have been unearthed in countless quantities, and evolving organisms have never been discovered; On the contrary, it is the "living fossils" that prove that no evolution has occurred.

It is a fact that living things are of their own kind. Yes, there are similarities between different species, but evolution is not the only one that can explain this phenomenon. A more plausible explanation is that different species are from the same creator, so they are both similar and different.

For example, the Volkswagen Beetle resembles the front of a Porsche, isn't it? Our most natural thought is that they come from the same designer, don't they? This is of course also true.

We wouldn't think the Beetle was converted from a Porsche, would we?

So, with such a simple and universal logic, why should we abandon the question of the origin of life and the origin of species? Even if there is no evidence for evolution, even if there is a lot of counter-evidence for evolution, they are still unwilling to give up.

In fact, this is what the Bible calls sin, and this sin is not moral, but we know that there is a God, but we deliberately do not admit it. It is also a source of death and suffering. But God did not give up on man, He loved everyone and even made His Son a man, named Jesus, to die for man.

There are basically these two complete narratives in this world. One is the theory of evolution, everything is random, our beginning is accidental, the process is farce, and the end is fertilizer. Everything has no meaning and value, and at most it is self-deception.

Another narrative is that there is value in our lives, that God created the world and us, and that He loves us deeply. The beginning of life is love, the process is love, and the end is love.

Hope it helps.
