How does a biome differ from a community?

Question

Ivy Ackerman · Accepted Answer

Biomes are a group of ecosystems, and caracterized by biogeographical constraints.
Communities are groups of species in the same place, at the same time.

A biome is an assemblage of multiple ecosystems with a common structure. Biomes are features of a biogeographic zone at the continental scale (including its climate), and they are classified according to the dominant flora and fauna of the zone. Each of these major types can be further subdivided (for example, marine and freshwater biome for the Aquatic type / tropical and temperate for the Forest type). The major types are: aquatic, deserts, forests, grasslands, and tundra (though not everyone agrees on this, depending on which environmental conditions are used to classify them). A community is a group of species present in a particular location and time, such as the fish community in the Northern Sea. The time and space scale can range from extremely local to regional, and the structure of a community is determined by interspecific relationships (predation, competition, etc.).

undefined A biome refers to a large geographic area characterized by similar climatic conditions, vegetation types, and animal species. In contrast, a community refers to the interacting populations of different species living within a specific habitat or ecosystem. While a biome encompasses multiple communities, each with its own unique composition of species, a community focuses specifically on the interactions between these species within a defined area. Additionally, biomes are classified based on broader ecological characteristics, such as temperature, precipitation, and vegetation, while communities are characterized by the specific species present and their interactions within a given ecosystem.
