Biomes can be defined as the major communities of the world, classified according to their predominant vegetation and characterised by adaptations of organisms to that particular environment. Biomes are composed of several ecosystems and represent a regional community of organisms named after the dominant vegetation. Ecologists do not always agree on the exact number of ecosystems and biomes, as the number will vary depending upon how the biomes are defined, for instance: according to species or according to the particular climate characteristics that are considered. Effective management and care of the biosphere require that we understand how organisms interact with the physical environment to create their habitats. Management involves understanding the scale at which such associations function and the processes that control the distribution of species within such systems. Ecosystems are communities of organisms that inhabit specific physical environments, defined primarily by their climate and landforms. A number of similar ecosystems can be grouped together in a biome, a regional community of plants and animals named after the dominant type of vegetation. Biomes are characterised by a similar association of species, comparable climates, and consistent soil types (Enviro-info 2001)
