Do you know what the biosphere is?
Biologically, the habitat which contains air, water and soil together make up the living world or the biosphere. It includes the entire surface of the earth and the water bodies. It also extends about 20 kilometers in height and about 11 kilometers in depth from the surface of the earth.
The ecosystem is the basic unit of biosphere. All the living organisms in an ecosystem together form the biotic community. Each specific population in a biotic community is called a species.
After observing any one of the ecosystems, record the components which include the biotic factors, abiotic factors and the different species in a biotic community etc in your science diary.
