Biological group system
The biological group system (Biotechnology) is a major classification of the types of communities of plants, animals and soil organisms. Both of the plant group (shikuzuku). It is defined based on factors such as plant composition (tree, shrub, grass), leaf form (hardwood, conifer), density (forest, savana) and other climates. Unlike biogeographical districts, genetic, taxonomic and historical similarities are not defined. Biological cluster systems are often determined by ecological transitions and extreme phases. Characteristics of biodiversity of each biomolecular system, in particular the diversity of fauna and the type of non-dominant plant, depend on abiotic factors and biomass productivity of dominant vegetation. Diversity of species tends to increase at higher basic productivity, humidity and temperature.
