Question

укажите главную функцию биосферы и поясните ,в чем она выражается

Answer 1

Главная функция биосферы заключается в обеспечении круговорота химических элементов, который выражается в циркуляции веществ между атмосферой, литосферой, гидросферой и живыми организмами. Динамическая гармония биосферы достигается уравновешиванием ее подсистем, которые постоянно взаимодействуют  друг с другом, путем  взаимного  приспособления.

Answer 2

Главная функция биосферы заключается в обеспечении круговорота химических элементов, выражается в циркуляции веществ.

Answer 3

The Main Function of the Biosphere

The biosphere refers to the part of the Earth's surface and atmosphere where living organisms exist. It encompasses all ecosystems, including forests, oceans, grasslands, and deserts. The main function of the biosphere is to support and sustain life on Earth. It plays a crucial role in maintaining the balance of various ecological processes and providing essential resources for living organisms.

How the Function of the Biosphere is Expressed

The function of the biosphere is expressed in several ways:

1. Biodiversity: The biosphere is home to an incredible diversity of species, from microscopic organisms to large mammals. This biodiversity is essential for the stability and resilience of ecosystems. It allows for the efficient cycling of nutrients, the pollination of plants, and the regulation of populations.

2. Energy Flow: The biosphere facilitates the flow of energy through food chains and food webs. Producers, such as plants and algae, convert sunlight into chemical energy through photosynthesis. This energy is then transferred to consumers, such as herbivores and carnivores, as they feed on other organisms. The energy flow within the biosphere is crucial for the survival and growth of all living organisms.

3. Nutrient Cycling: The biosphere plays a vital role in the cycling of nutrients, such as carbon, nitrogen, and phosphorus. Through processes like decomposition, nutrient-rich organic matter is broken down and recycled back into the environment. This recycling ensures that essential elements are continuously available for the growth and development of living organisms.

4. Climate Regulation: The biosphere helps regulate the Earth's climate by absorbing and releasing greenhouse gases, such as carbon dioxide (CO2), ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2). These gases influence the Earth's temperature and weather patterns. Forests, for example, act as carbon sinks, absorbing CO2 and reducing its concentration in the atmosphere.

5. Ecosystem Services: The biosphere provides numerous ecosystem services that are essential for human well-being. These services include the provision of clean air and water, the regulation of pests and diseases, the pollination of crops, and the provision of food and raw materials. The biosphere's ability to provide these services is crucial for the sustainability and survival of human societies.

In summary, the main function of the biosphere is to support and sustain life on Earth. It does so by maintaining biodiversity, facilitating energy flow and nutrient cycling, regulating the climate, and providing essential ecosystem services. The biosphere is a complex and interconnected system that plays a vital role in the overall functioning of our planet.
