What is the smallest biosphere on Earth?

The Earth's surface is made up 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 the environment in which they live.

The lithosphere includes the soil, 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 meters, are the deepest terrestrial organisms known.

Organisms are found almost everywhere in the hydrosphere, but there are more species and numbers of organisms in the surface and bottom. 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.

Organisms in 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 above 5,000 meters. The main factors limiting the distribution of organisms to the upper altitudes are hypoxia, water shortage, low temperature and low atmospheric pressure. Due to the atmospheric environment, some insects can be carried to high altitudes, and bacteria and fungi have been found even in the stratosphere at 22,000 meters.

Because it is impossible for the altitude above 10,000 meters to provide conditions for living things to live for a long time, 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 its natural state, the biosphere gradually develops into a dynamic equilibrium system in which its components coordinate and compensate for each other through the circulation of matter and the flow of energy.

But this balance is fragile and vulnerable. For example, a large amount of nitrogen and phosphate fertilizers are injected into water bodies, resulting in excessive "fertile" of rivers and "eutrophication". Indiscriminate deforestation and blind reclamation of grasslands have led to soil erosion and accelerated the process of desertification.

These are all examples of human disruption of the dynamic balance of the biosphere.

Isn't the biosphere all about Earth?

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.

The biosphere is a unified whole formed by all organisms on the earth and the environment in which they live, and is the largest ecosystem, and the scope of the biosphere is: the bottom of the atmosphere, most of the hydrosphere, and the surface of the lithosphere.

It includes all the organisms on the earth and the entire environment in which they live, it includes the bottom of the atmosphere, most of the hydrosphere and the surface of the lithosphere<>

It provides the basic conditions for the survival of organisms, such as nutrients, sunlight, air, water, suitable temperature and a certain living space, which is suitable for the survival of organisms, and we must protect it well, and it is the unshirkable responsibility and obligation of every citizen to protect the biosphere.

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.

The biosphere, the ecosystem is; Two distinct categories. Ecosphere refers to the general term of the ecological factors of the whole earth; An ecosystem is a factor or a part of the ecosphere.

Biosphere is a general term for all biological chains, which includes biological chains and all subtle biological and ecological environments, ecosystems, etc. The biosphere is the largest ecosystem on Earth and the largest living system. The biosphere is the integrated whole of all ecosystems on Earth and is 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. From a broad perspective of geology, the biosphere is a global system of life and subsidy, including the interaction of living organisms 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.

Ecosystem is the abbreviation of ecosystem, which refers to a unified whole composed of organisms and the environment in a certain space in nature, in which organisms and the environment influence and restrict each other, and are in a relatively stable state of dynamic equilibrium in a certain period of time. The scope of ecosystems can be large or small, intertwined, and the solar system is an ecosystem, and the sun is like an engine that continuously provides energy to the solar system. Earth's largest ecosystem is the biosphere; The most complex ecosystems are tropical rainforest ecosystems, where humans mainly live in artificial ecosystems dominated by cities and farmland.

Ecosystems are open systems, and in order to maintain their own stability, ecosystems need to continuously input energy, otherwise there is a danger of collapse; Many basic substances continue to circulate dust rings in ecosystems, among which the carbon cycle is closely related to the global warming effect, and ecosystems are a major structural and functional unit in the field of ecology, which belongs to the highest level of ecological research.

Right. The biosphere is a unified whole composed of organisms and the environment, including forest ecosystems, marine ecosystems, farmland ecosystems, grassland ecosystems, freshwater ecosystems, wetland ecosystems, urban ecosystems, etc., is the largest ecosystem, it includes all the organisms on the earth and all the environment for their survival, it provides nutrients, sunlight, air, water, suitable temperature and a certain living space and other basic conditions for the survival of organisms, suitable for the survival of organisms. It consists of three parts: the bottom of the atmospheric circle, the majority of the hydrosphere, and the surface of the lithosphere.

The biosphere is the largest ecosystem on Earth.

The biosphere was first proposed by the Austrian geologist Hughes (in 1875) and refers to the whole of the Earth's areas of life and its habitation. It reaches an altitude of approximately 23 km above the surface and extends to a depth of 12 km below the surface and includes the lower stratosphere, the entire troposphere, and the sedimentary lithosphere and hydrosphere. But the vast majority of organisms usually live in areas about 100 meters thick above the Earth's land and below the surface of the oceans.

The biosphere is mainly composed of three parts: living matter, biogenic pona only matter and biologically inert matter. Living matter, also known as living matter, is the total sum of biological organisms. Biogenesis is the organic mineral and organic product of biological matter, such as coal, stone or oil, peat and soil humus, etc.; Biologically inert substances refer to gases, sedimentary rocks, clay minerals, and water in the lower layers of the atmosphere.

The biosphere is a complex, global, open system, a self-regulating system of living and non-living matter.

Ecosystem Types:

1. Wetland Habitat and Cultivation System: Water purification and flood storage and drought prevention are known as the "kidneys of the earth", among which swamps are typical wetland ecosystems.

2. Forest ecosystem: conserving water sources, maintaining water and soil, preventing wind and fixing sand, regulating climate, purifying air, etc., it is known as "green reservoir" and "lung of the earth".

3. Grassland ecosystem: soil and water conservation, windbreak and sand fixation.

4. Urban ecosystems: Humans play an important role in the debate.

5. Farmland ecosystem: It requires a lot of manpower and material resources.

6. Freshwater ecosystem: providing drinking water, irrigation and industrial water, regulating climate and other functions.

7. Marine ecosystem: The vast sea level absorbs a large amount of carbon dioxide and produces a large amount of oxygen, accounting for 70% of the earth's oxygen production.

The biosphere is located in the Earth's outer sphere. The structure of the geosphere is divided into two parts: the outer sphere of the earth and the inner sphere of the earth, the outer sphere can be further divided into three basic spheres: the atmosphere, the hydrosphere and the biosphere, and the inner sphere can be further divided into three basic spheres: the crust, the mantle and the core, and the top of the crust and upper mantle are collectively called the lithosphere.

The biosphere refers to the area on the earth that allows all the occurrence and feel the impact of life activities, and is the unique circle of planetary earth, and the biosphere is the largest ecosystem on the earth.

The biosphere is a general term for surface organisms including microorganisms and their bottom-up environment, and the scope of the biosphere is: the bottom of the atmosphere, most of the hydrosphere, and the surface of the lithosphere.

The biosphere is the largest ecosystem and the most hungry living system on Earth, thriving a wide variety of life and having the ability to self-regulate.
