Continuous ecosystems covering very large areas, such as the northern coniferous forest or the steppe grassland are known as biomes. q.v." (B73)

Fundamental concept include the flow of energy via food chains and food webs, and the cycling of nutrients biogeographically. Ecosystem principles can be applied at all scales - thus principles that apply e.g. to an ephemeral pond can be applied equally to a lake, an ocean, or the whole planet. In Soviet and Central European literature "Biogeocoenosis" describes the same concept." (B80)
