Features of the biosphere level. The doctrine of the biosphere
The biosphere is the shell of the Earth inhabited by living organisms and changed by their activity. The scientist who developed the idea in depth was V. I. Vernadsky, who showed that the present look of the Earth – the composition of the atmosphere, sedimentary rocks, soil – was shaped by living organisms. Other levels of life (cell, organism, population, ecosystem) are parts of the biosphere; it is their most complex and largest unit, and its structural unit is the biogeocenosis. Planet-wide processes occur in the biosphere: continuous capture of solar energy, release of oxygen by plants, maintenance of the ozone layer, a relatively constant level of carbon dioxide, and the cycling of matter. The stability of the biosphere is not fixed immobility but dynamic balance: the flow of matter and energy never stops, yet their overall balance is kept. Modern biology studies global problems at the biosphere level, such as oxygen production, climate change and the conservation of biological diversity.
Draw the chain of life levels in your notebook (cell → organism → population → biogeocenosis → biosphere) and write one example from your own surroundings for each link. Safety: paper work only.
