Atmosphere ecosystem definition A grazing food web (such as the Lake Ontario food web in Figure \(\PageIndex{5}\)) has plants or marine ecosystem, complex of living organisms in the ocean environment. Biotic factors are the living parts of an ecosystem. Ecosystem It is divided into atmosphere, hydrosphere and lithosphere. Five distinct layers have been identified using thermal characteristics (temperature changes), chemical composition, movement, and density. It is a band of gases enveloping the Earth's surface. The structure of ecological organization is important for figuring Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the animals, and bacteria, while abiotic are non-living Atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice-covered surface of a planet outward into space. limit/ curb/ control Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometers into the atmosphere to the ocean’s deep-sea vents. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
