Question

write short note on earth biosphere above 80 words​

Answer 1

Answer:

The Biosphere --contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth. Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes.

Geochemists define the biosphere as being the total sum of living organisms (the "biomass" or "biota" as referred to by biologists and ecologists). In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being geosphere, hydrosphere, and atmosphere. When these four component spheres are combined into one system, it is known as the Ecosphere. This term was coined during the 1960s and encompasses both biological and physical components of the planet.[7]

The Second International Conference on Closed Life Systems defined biospherics as the science and technology of analogs and models of Earth's biosphere; i.e., artificial Earth-like biospheres.[8] Others may include the creation of artificial non-Earth biospheres—for example, human-centered biospheres or a native Martian biosphere—as part of the topic of biospherics.

A short note on Earth Biosphere is as follows:

• The environment of the Earth is divided into four components namely the lithosphere, tge hydrosphere, the atmosphere and the biosphere.
• We can define biosphere as the zone of the Earth where life exists due to the interaction of all the components of life i.e. air, water and land.
• Biosphere is that region on the planet Earth where life is possible.
