Question

Why is the biosphere important for living organisms?

Answer 1

Hint: For living organisms, the biosphere is significant, since three basic elements of life (land, water, and air) are found here. Existence, which is peculiar to this planet, occurs in that zone. The biosphere is a layer of life support that surrounds the earth and makes life possible without any protective equipment for plants and animals.

Complete answer:
The biosphere is the narrow interaction zone between the air, water, and soil. In an ecosystem, it provides habitat. For example, wetlands located at the confluence of hydrosphere and lithosphere provide fertile grounds for breeding and healthy habitat, resulting in high species diversity. Species and communities may occur in a specific niche.

Significance of the biosphere:
-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. For example, tropical rainforests are highly stable due to their high diversity and complex dependency.

-For example, rivers provide water and their banks become places for settlement, forests provide timber, the soil becomes the basis for agriculture, it provides tools to humanity using which man has developed and modified the physical environment according to his cultural needs.

-The biosphere is therefore important for the survival and life of living organisms. Since biosphere components are intricately connected with each other, one shift leads to a feedback mechanism in the system, as is evident in the increasing concentration of GHG in the atmosphere that affects the primary producers' photosynthesis process, land degradation due to increased run-off, etc. This has a detrimental effect on the entire biosphere, threatening the survival of organisms that, including those living in ecotone regions, have a limited tolerance range.

Therefore, conservation is important, particularly buffering from human activities, by maintaining a balance between elements of the biosphere. This can be done through various means:
-The principle of Biodiversity Conservation
-The formation of national parks
-The regulation of resource use such as the Coastal Regulation Zone
-The Environmental Impact Assessment
-The restoration of degraded sections of the biosphere such as afforestation
-The adoption of sustainable development practices in the cultural modification of the environment by man.

Note: The biologist Edward O. Wilson, who coined the word biodiversity, conservatively estimated that at least 27,000 species became extinct every year in the late 20th century. Tiny tropical species were the bulk of these.
