Question

write a short note on biosphere ​

Answer 1

Answer:

The biosphere is one of the four layers that surround the Earth along with the lithosphere (rock), hydrosphere (water) and atmosphere (air) and it is the sum of all the ecosystems. The biosphere is unique. So far there has been no existence of life elsewhere in the universe. Life on Earth depends on the sun.

Answer 2

Four domains of the earth which interact with each other are the Atmosphere (Air), the Biosphere (life), the Lithosphere (land) and the Hydrosphere (water).

Here, we'll discuss the Biosphere.

• The biosphere is that narrow zone where land, water and air come in contact with each other .
• The biosphere makes the earth a unique planet as life exists only in the biosphere.
• It is that part of the Earth where all living organisms exist.
• It is the part of the Earth where the Lithosphere, Hydrosphere and Atmosphere coexist.
• The biosphere has distinct zones or ecosystems having their own climate, animals and plants.
• In every ecosystem, there is a very delicate balance between the physical environment (the land, water and air) and the biological environment (plants and animals). They are both dependent. If the physical environment changes, it will also change the biological environment (plants and animals life).
• A combination of soil conditions, water availability and atmospheric conditions like temperature decide the kind of life that can survive in any part of our planet.
