Question

Biosphere is important for the survival of human life. Explain.

Answer 1

Biosphere-

1. The biosphere is the region of the earth where life occurs.
2. It has different parts like land, water, and air that sustain life on earth.
3. The biosphere is a large area on the earth where all sort of life exists and it is conserved for unusual scientific and natural interests.

Importance of Biosphere-

1. The biosphere provides a base for the food chain, a food network in which material and energy are distributed through animals, contributing to complex systems that help to sustain the environment and the survival of species.
2. Living organisms are required to adapt to the environment of the biosphere.
3. For example, tropical rainforests are highly stable due to their high diversity and complex dependency. Rivers provide water and their banks become places for settlement, forests provide timber, and the soil becomes the basis for agriculture.
4. It provides tools to humanity using which man has developed and modified the physical environment according to his cultural needs.
5. Since biosphere components are intricately connected with each other, one shift leads to a feedback mechanism in the system.
6. It is evident that in the increasing concentration of Green House Gases in the atmosphere affects the primary producers' photosynthesis process, land degradation due to increased run-off, etc.
7. This has an opposite effect on the biosphere, leading to the threat to the survival of organisms.
8. Therefore, the conservation of the Biosphere is important.
