why is the biosphere important for living organisms
Answers
Answer:
Biosphere is important for living organisms because it is termed as the zone of life on earth. ... There is a very narrow zone on Earth where land, water and air come in contact with each other. This is called biosphere. All the living things such as plants, animals, and human being exist only in this zone

10 reasons that justify the importance of the biosphere
1- Produce organic matter
Through oxygenic photosynthesis, the production of oxygen and nitrogen That occurs in the biosphere is responsible for virtually all biochemical processes of organic matter production through the complete carbon cycle, involving both terrestrial and oceanic substrates.
2 - Allows life on earth
The biosphere is literally the living layer that covers the earth's surface. This includes the most superficial part of the Earth crust , As well as rivers, seas, lakes, oceans and even the lowest part of the atmosphere. The balance between all these parts allows the existence of life on earth, including humans .
3- Provides food and raw material
The biota, that is, the living elements of the biosphere, is the vital component that provides humanity with the raw material it needs to survive: food, fiber and fuel .
4- Cleans the environment of toxins
Through the natural cycles of decomposition of biological modification, in the biosphere the planet earth gets rid of toxins and components that, in excess, can be harmful to life. Thus, carbon dioxide, for example, is used in the process of photosynthesis And organic wastes are reused by biota.
5- It is the substrate of the food chain
The food chain Is the biological chain that exemplifies the current of energy and nutrients that are established in the different species of an ecosystem. As all living beings inhabit the biosphere, this is the vital element for the survival of species.
6- Conserve biodiversity
By means of biosphere reserves designated by Unesco as areas composed of terrestrial, marine and coastal ecosystems recognized by UNESCO's Man and the Biosphere Program .
7- Maintains the original environment of indigenous peoples
Societies that live from ancient times in close contact with nature need the conservation of the biosphere for their existence.
The participation of local communities in the conservation and preservation of environment (And the biosphere with it) allows its own survival and conservation of its original traditions and ways of life.
8- Provides pharmaceutical compounds
In fact, all the compounds used in the pharmaceutical industry today are derived to a greater or lesser extent from compounds found naturally in the terrestrial biosphere.
Recurrent biological research in areas of high biological density such as Southeast Asia and the Amazon in South America has provided researchers with new elements that have been implemented in pharmaceutical treatments and medicines ranging from chemotherapy to beauty treatments.
9- May serve as a marker of contamination
The study and control of its composition can function as an efficient and adequate marker to control the levels of terrestrial pollution and to verify if in fact public policies and international agreements have had a real and positive impact on the current levels of planetary pollution.
Thus, from the information extracted from the study of the biosphere can establish historical and perhaps even interregional comparisons that show changes and variations in levels and ecosystems affected by pollution .
10- Can help to track pollutants
The study of the composition of the biosphere can show exactly what they are and how the pollutants caused by anthropogenic action on Earth act.
In this way, States and international organizations can initiate research and public policies that are appropriate to the pollutants present in the environment that they intend to preserve.
