Answer:

Ecosystem. In biology, an ecosystem is a community of organisms and their physical environment. The notion of an ecosystem recognizes the many ways that an organism interacts with and depends on various parts of its environment. ... The idea of an ecosystem has been adopted for social and economic systems.

Explanation:

While organisms in an ecosystem may be engaged in competition or predation, the concept focuses on interdependence — one organism's reliance on another or on the ecosystem as a whole.

The idea of an ecosystem has been adopted for social and economic systems. An "ecosystem" is the environment that a company is part of, including suppliers, partners, consumers, and the underlying structure and behavior of the technology, markets and social context. Framing economic interactions as being an ecosystem promotes establishing alliances with companies that might have been seen as competitors. There are many possible economic relationships, just as there are many possible relationships between organisms in a biological ecosystem.

One can contrast the use of the term "ecosystem" with that of "system," which focuses on the collective behaviors. "Ecosystem" is typically used in discussing the internal dependencies of the larger system especially as they pertain to a particular part. For example, one might say "A is part of B's ecosystem" to recognize B's dependence on A in the larger context. Thus, "ecosystem" is almost a substitute for the term "environment," but it emphasizes the existence of various parts of the environment, rather than the environment as a single entity.

Still, in ecology, the term also alludes to whole-system collective behaviors, such as the forest lifecycle that might include destruction by fire and stages of regrowth.

The idea of an ecosystem means viewing an organism, corporation, or other entity as part of a larger system whose parts are interacting and interdependent.

Answer:

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.[2] These biotic and abiotic components are linked together through nutrient cycles and energy flows.[3] Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.[4]

Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem.[5] Unlike external factors, internal factors are controlled, for example, decomposition, root competition, shading, disturbance, succession, and the types of species present.

Ecosystems are dynamic entities—they are subject to periodic disturbances and are in the process of recovering from some past disturbance.[6] Ecosystems in similar environments that are located in different parts of the world can end up doing things very differently simply because they have different pools of species present.[5] Internal factors not only control ecosystem processes but are also controlled by them and are often subject to feedback loops.[5]

Resource inputs are generally controlled by external processes like climate and parent material. Resource availability within the ecosystem is controlled by internal factors like decomposition, root competition or shading.[5] Although humans operate within ecosystems, their cumulative effects are large enough to influence external factors like climate.[5]

Biodiversity affects ecosystem functioning, as do the processes of disturbance and succession. Ecosystems provide a variety of goods and services upon which people depend.
