Biome. A biome (/ ˈbaɪ.oʊm /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1][2] Biomes may span more than one continent. A biome encompasses multiple ecosystems within its boundaries.
Outline of ecology. The following outline is provided as an overview of and topical guide to ecology: Ecology – scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment. The environment of an organism includes both ...
