System Analysis Of Environment Essay

An environment is a community of entities, biotic and abiotic, with networks of relationships, associations and affinity between them. The kinship between the living organisms and their surroundings is so complex and dynamic that in order to better understand the correlations between them, the environmental scientists use the system analysis approach. A system is a set of interconnected parts which function together as a complex whole’ [Smithson, The Physical Environment, pg 9]. It is a holistic phenomenon which believes that all the processes involved among the elements are interlinked and that one would rarely function without the existence of the other. The system further contains subsystems or components and within them are stores. A flow of energy and matter move inside the systems; this energy or material can stay inside the stores where they can be altered through biogeochemical cycles. The system analysis approach focuses on

Not only does it provide the air that living organisms breathe; it is also one of the most influential element responsible for the synthesis of weather and climate through the exchange of energy. It provides a shield to the organisms from the malign effects of the solar radiation. Atmosphere interacts with other spheres in varied ways e.g water from the ocean evaporates into the air (hydrosphere), humans breathe in air (biosphere),

The third component of the earth system is the biosphere. Biosphere is a large ecosystem which supports all forms of living and nonliving elements. Plants, animals, humans depend on the biosphere for their existence. The biosphere is able to provide this medium via its interaction with all the other components of the earth system. Where hydrosphere provides water for all the living organisms, soil and minerals are provided to the vegetation and biota via geosphere, air for the living organisms to breathe is supplied by the
