Diagram of Ecosystem Components

Figure 2.1. Schematic representation of an ecosystem or a biogeocenose (framed) in a state of exchange with the environment. If it is possible to recognize a distinct boundry to the ecosystem, for example, the edge of a woodland, then the area enclosed by the frame would constitute a biogeocenose .
