what is biome:
A biome is an ecological community that lives in a certain area. As such, biomes are different each other by the type of flora, fauna and climate that predominates in them. In this sense, the biome is the expression of ecological conditions of a place to be inhabited by certain species of animals and plants. From there who also know them is as landscapes bioclimatic or biotic areas.
Some of the factors that influence an area to develop certain type of biome are the variables of latitude, altitude, temperature and rainfall, which determine the climate of a place. In addition, other aspects, such as the structure of plants, the space of these together, its kind of foliage and soil type, are also factors associated with the configuration of a biome.
The Earth, in this sense, can be subdivided into biotic zones according to the climatic characteristics that are present. Thus, in each area a characteristic type of vegetation and fauna, whose interrelation constitutes a biome develops.
Biomes can be divided into two major groups: the land and the water, and these, in turn, are subdivided into many others. Among the terrestrial biomes, for example, can be distinguished the rainforest, temperate forest, savanna, steppe, tundra, desert, among others.
Freshwater ecosystems can be counted among the water, for its part, (lentic: Lakes, ponds, wetlands, and lotic: rivers and streams), the marine waters (Oceans, intertidal areas, and coral reefs), and brackish ecosystems (estuaries, salt marshes and mangroves).
Moreover, the scientific discipline responsible for the description, study and analysis of terrestrial biomes is biogeography.
The word biome, as such, is derived from the Greek βιο (bio), meaning ‘life’. The concept is, however, relatively recent in the areas of ecology and biology. As such, it was coined by the American ecologist Frederic E. Clements, who defined the biome as a community of plants and animals.
