What is the biosphere? Please tell me

The concept of the biosphere.

The concept of the biosphere was first proposed by the Austrian geologist Hughes (in 1375) and refers to the whole of the earth's areas of life and its habitation. It reaches an altitude of roughly 23 km above the surface and extends to a depth of 12 km below the surface, which includes the lower stratosphere, the entire troposphere, and the sedimentary lithosphere and hydrosphere. However, the vast majority of organisms usually live in areas about 100 m thick above the Earth's land and below the surface of the oceans.

The biosphere is mainly composed of three parts: living matter, biogenerated matter, and biologically inert matter. Living matter, also known as living matter, is the sum of living organisms; Biogenesis are the products of organic mineral interactions composed of living matter, such as coal, oil, peat, and soil humus. Biologically inert substances refer to gases, sedimentary rocks, clay minerals, and water in the lower layers of the atmosphere.

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. ]

The biosphere is the largest ecosystem on Earth that is made up of all living things and their environment

The biosphere refers to the area on the earth where the impact of life activities appears and feels, is the general term for surface organisms including microorganisms and their bottom-up environment, is the unique circle of the planet earth, it is also the space where human beings are born and live, and the biosphere is the largest ecosystem on the earth.

The sum of all living things on Earth and their environment is called the biosphere.

The biosphere is a general term for all biological chains, which includes the biological chain and all the subtle biological and ecological environments, ecosystems, etc. The biosphere is the largest ecosystem on Earth and the largest living system.

The biosphere is an integrated whole of all ecosystems on Earth, an outer sphere of the Earth that extends approximately 10 kilometers vertically above and below sea level. It includes air, land, lithosphere, and water on Earth where life exists and is changed and transformed by life processes. 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 biosphere 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. It is also the space where human beings are born and live.

The extent of the biosphere is: the bottom of the atmosphere, most of the hydrosphere, and the surface of the lithosphere.

The biosphere (also known as the biosphere) is the largest ecosystem on the Earth's surface composed of the lower atmosphere, hydrosphere, soil lithosphere, and the organisms that live in it.

In the process of long-term evolution, the earth has formed different spheres such as the atmosphere, hydrosphere, and soil lithosphere, which overlap each other, penetrate each other, and interact with each other to form an environment suitable for the survival of organisms with gas in water, water in air, and water and gas in soil. Organisms rely on the material and solar radiation energy provided by the three circles to survive and develop, and at the same time, in the process of development, they constantly modify the composition and properties of each circle. The three inanimate physical spheres on the Earth's surface constitute the biosphere only after the emergence of living organisms and the active penetration of life into each other.

How big is the biosphere? The biosphere is 23 km above the Earth's surface and 11 km down (the deepest trough in the Pacific Ocean).

The Earth's surface is composed of the atmosphere, hydrosphere and lithosphere, of which the area suitable for living organisms is called the biosphere. The extent of the biosphere roughly includes the lower layers of the atmosphere, the upper layers of the lithosphere, and the hydrosphere. The biosphere is the general term for all living things on the earth and their living environment.

The lithosphere includes the soil, and most of the organisms in the lithosphere live within a few tens of centimeters of the upper layer of the soil, and the roots of plants can reach deeper into the soil. The main factors limiting the distribution of life to the deeper layers of the soil are the lack of oxygen and light. Oil bacteria, which live at depths of 2,500 to 3,000 metres, are the deepest known terrestrial organisms.

Organisms are found almost everywhere in the hydrosphere, but there are more types and numbers of surface and bottom organisms. The main factors limiting the distribution of organisms in the deep sea are lack of light, hypoxia and increasing pressure with depth. However, there is still deep-sea life in the deepest part of the ocean above 11,000 meters.

The gas ring is made up of various gases, with nitrogen and oxygen being the most abundant. The organisms of the atmosphere are mainly distributed at the bottom, and most birds can only move in the air below 1,000 meters, and only a few can fly to an altitude of more than 5,000 meters. The main factors limiting the distribution of organisms to the upper altitudes are hypoxia, water scarcity, low temperature and low atmospheric pressure.

Due to the atmospheric environment, some insects can be carried to high altitudes, and bacteria and fungi can be found even in the stratosphere at 22,000 meters. Because the altitude above 10,000 meters cannot provide long-term living conditions for living organisms, the space is called the subbiosphere.

The biosphere is a system that constantly circulates matter and energy flows, and has a certain regulatory function. In the natural state, the biosphere gradually develops into a dynamic equilibrium system in which the various components coordinate and compensate for each other through the circulation of matter and the flow of energy. However, this balance is fragile and vulnerable.

For example, a large amount of nitrogen fertilizer and phosphate fertilizer are injected into the water body, resulting in excessive fertility of rivers and eutrophication. Deforestation and blind reclamation of grasslands lead to soil erosion and accelerate the process of desertification. These are all examples of human disruption of the dynamic balance of the biosphere.

The biosphere is the children of the atmosphere and the hydrosphere, and after their birth, they are nurtured by their parents, the atmosphere and the hydrosphere, and the two "relatives" of the terrasphere and the lithosphere, who also directly or indirectly support them, so that they can grow and reproduce.

The biosphere is a whole and the largest biological system that combines living and non-living things.
