Scientists have discovered that there is an underground biosphere on Earth, and what kind of organis

Scientists have found some underground creatures, but only a few hundred meters, they only live on the surface of the earth, and have not reached the depths of the earth's core.

Because there is no sunlight and there is not enough oxygen in the underground, the organisms living here are anaerobic organisms, and the number of them reaches several millions, including many bacteria.

Ants, rats, earthworms, snakes, watermelon insects, these creatures live in the land and are common animals in the underground biosphere.

Except for the biosphere on Earth.

In addition, the atmosphere is obvious.

lithosphere, hydrosphere;

At the same time, from the earth and from outside the earth, there are also the aperture, the electric sphere, the gravitational sphere, and the magnetosphere.

And what affects almost every creature is the circle of friends.

In addition to the biosphere, there is also the atmosphere, lithosphere, and hydrosphere.

Answer: Atmosphere, hydrosphere, lithosphere.

The structure of the Earth's sphere is divided into two parts: the Earth's outer sphere and the Earth's inner sphere.

The Earth's outer sphere can be further divided into three basics.

The sphere, i.e., the atmosphere, hydrosphere, biosphere.

The Earth's inner sphere can be further divided into three fundamental layers, namely the crust, mantle, and core. The top of the Earth's crust and upper mantle (above the asthenosphere) is made up of hard rocks, collectively known as the lithosphere.

The Earth's surface is composed of the atmosphere, hydrosphere and lithosphere, and the biosphere is the most suitable area for living organisms in the three circles.

There is an underground biosphere on Earth, is it possible that there are more advanced organisms besides microorganisms? Yes. I personally believe that the subterranean biosphere does exist, but they are all prokaryotic microorganisms (i.e., different species of bacteria), not cellular organisms, and therefore, there is no higher biological phenomenon.

Why do you say that? Because where there are living organisms in nature, where they exist, they survive. All cellular organisms born from cells and bacterial microorganisms on the earth survive on the surface of cellular organisms, and there is almost another type of germ microorganisms in the body, accounting for about 5% of the life space of cellular organisms.

<> under the high-pressure ocean, under the high-temperature and high-pressure underground surface, there can be simple life, but not the most advanced organisms, and some books have more superficial descriptions of underground civilizations. Scientists realize that life underground helps humans understand the mysteries of life more deeply, which is of great help to the study of life under extreme conditions. Our planet is the only planet known to contain life, and it has long been thought that life on Earth is mainly concentrated on the surface of the earth, and outside of the earth, it is concentrated in a "dark world" where the stove has died.

The reason is simple: not only is there no sunlight in the depths of the earth, but it is also flooded by high temperatures and pressures. Life must be impossible in such a harsh environment.

Underground coal seams can be considered as biotics (this should be an organic alternative) The formation of coal has nothing to do with the earth's organisms and trees, such as the Qijiang Coal Mine in Heilongjiang Province, where seven layers of coal overlap, one layer is rock, the other layer is coal, the coal is rock, there is no coal in the rock, and there is no rock. There are currently 200 billion stars in the known Milky Way, 10% of which are similar to the yellow stars of the Sun; of which the earth group accounts for 10%; 10% of them are suitable for living in the atmosphere... In the end, it can be concluded that this is ...

It is likely that the 200,000 stars in the Milky Way that contain intelligent beings will have bacteria, and if the number of bacteria is large enough, then the planet's surface will be purple and through telescopes will be purple.

Solution: Organisms need nutrients, sunlight, air and water for survival, as well as suitable temperature and a certain living space

The biosphere is a unified whole composed of organisms and the environment, which includes all the organisms on the earth and the entire environment in which they live, including the bottom of the atmosphere, most of the hydrosphere and the surface of the lithosphere.

1. Why organisms on earth can only live in the biosphere ( ) A biosphere can provide the basic conditions for the survival of organisms.

b It can provide organisms with a suitable temperature and a certain amount of survival space c It can provide nutrients for organisms.

d Sunlight, air and water and nutrients exist only in the biosphere.

The biosphere is a unified whole formed by all organisms on the earth and their suitable environment, the scope of the biosphere: divided by sea level, the biosphere can reach an altitude of about 10 kilometers upwards, and can go deep into a depth of about 10 kilometers downward, with a thickness of about 20 kilometers, including the bottom of the atmosphere, most of the hydrosphere and the surface of the lithosphere, of which there are organisms almost everywhere in the hydrosphere

Therefore, the answer is: all living things form a unified whole with their suitable environment

The Earth is speculated to have survived for 4.6 billion years, but how long will it live?

Scientists believe that if the earth is allowed to move freely, I am afraid that it will exist forever, but if other external factors interfere with it, the earth may have its end of life.

The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth. Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. In the 30s of this century, when physicists learned the mystery of the sun's luminescence, the situation was very different.

It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main sequence star phase, the red giant Zen Qingqi star phase, and the compact star phase. The main sequence phase is the period of stability of the Sun. This phase will last for 10 billion years.

At present, the sun is only halfway through and is in middle age. Once the Sun reaches the red giant stage, then the end of the Earth is coming. Of course, this is billions of years away.

Some scientists believe that the Sun may have a brother, a companion star of the Sun, which orbits the Sun day and night, and turns to the closest place to the Sun every 26 million years"Make waves"Its strong gravitational pull will cause a large disturbance of many comets, and 1 billion comets will be on a rampage in the solar system, and the Earth and other planets will become these comets"Target"。If the mass of the comet that collides with the Earth is large enough, the consequences are unimaginable: the extinction of light organisms and the upheaval of ecology; Heavy landslides and earth cracks, the earth"Broken bones"。

However, this solar companion star, which could bring misfortune to Earth, has not been discovered, although many scientists believe it exists.

The biosphere is the largest ecosystem on Earth.

The biosphere refers to any area on Earth where the effects of life are felt and felt. It is a general term for surface organisms, including microorganisms and their bottom-up environment, and is a unique sphere of planet Earth. It is also the space where human beings are born and live.

The biosphere is the largest ecosystem on Earth.

In the broad sense of geology, the biosphere is a global ecosystem that unites all living things and the relationships between them, including their interactions with the lithosphere, hydrosphere and air.

The biomass bending and collapse circle is a closed and self-regulating system. Earth is the only known place in the entire universe where living beings live. The biosphere is thought to have evolved after the origin of life 3.5 billion years ago.

The biosphere is the main place where natural disasters occur, and it derives environmental and ecological disasters. The biosphere is the area on the earth where the impact of life activities is felt and is felt, and it is the general term for the surface organisms, including microorganisms and their bottom-up environment, and is the unique sphere of the planet Earth.

Existential conditions:

Clause. First, sufficient light energy from the sun must be obtained. Because all life activities need energy, and its basic ** is solar energy, green plants absorb solar energy to synthesize organic matter and enter the biological cycle.

Clause. Second, there should be a large amount of liquid water that can be bioused. Almost all living things contain a lot of water, and there is no life without water.

Clause. 3. There should be temperature conditions suitable for life activities in the biosphere, and there are three kinds of changes in the substances within this temperature change range: gaseous, liquid and solid.

Fourth, it provides various nutrients needed for living matter, including O2, CO2, N, C, K, CA, FE, S (oxygen, carbon dioxide, nitrogen, carbon, potassium, calcium, iron, sulfur), etc., which are the composition or intermediary of living substances.

In short, all places on Earth where life exists belong to the biosphere. The essentials of the biosphere were first proposed by the Austrian geologist Hughes (in 1875) and refer to the whole of the earth's areas of life and its habitation.
