Difference between Biome and Ecosystem
Biome and ecosystem are two different ecological concepts. Although they are closely related to each other, they are different from each other. Let us see how they differ from each other!
Biome refers to a large geographical area with similar plants, animals, organisms etc., adapted to the climate and terrain of that area. It is generally named after the predominant vegetation found in it, e.g. tropical rainforests, mid-latitude deciduous forest, coniferous forests etc.
Each biome has a distinct climate that decides the types of plants and animals found in that biome. So, different biomes have different types of species of plants and animals. Species of one biome may not survive the climate of other biomes. Biomes located at lower latitudes tend to be warmer and wetter than those located at higher latitudes.
A biome may have many ecosystems with similar climatic conditions, e.g. an aquatic biome may contain ecosystems like coral reefs, kelp forests etc. A biome can be terrestrial (land-based) and aquatic (water-based). Some of the terrestrial biomes are desert, tundra, rain forest, coniferous forest, temperate deciduous forest etc. Similarly, some of the aquatic biomes include lotic freshwater, lentic freshwater, Open Ocean, estuary, gulf, continental shelf water etc.
An ecosystem is a part of a biome. It refers to the interaction between abiotic (non-living) and biotic (living) components in a given area. The biotic factors include plants, animals, organisms etc., and abiotic factors include soil, water, sunlight, temperature, weather, climate etc. The biotic components interact among themselves through processes like predation, competition, parasitism, symbiosis etc., and with their abiotic components. The interaction between living species and their environment facilitates and maintains the flow of matter and energy in an ecosystem.
Based on the above information, some of the key differences between biome and ecosystem are as follows:
