BIO 121 Study Guide - Quiz Guide: Soil Fertility, Biome, Organism
Document Summary
Biome -> major regional complex of similar communiies. Large-scale ecological unit recognized primarily by dominant plant type and vegetaion structure. Depends on temperature, precipitaion, soil condiions, and paterns of circulaion in wind and water. Climate diagrams (climatographs) -> depict informaion on temperature (red) and precipitaion (blue) Broad-leafed trees that lose leaves in fall and remain dormant in winter. Much of europe, eastern china, and eastern north america. More extreme diference between winter and summer. West north america, coastal paciic northwest region. Ferile soils but suscepible to landslides and erosion. Central/south america, southeast asia, west africa, as well as other tropical regions. Dark and damp interiors, lush vegetaion, highly diverse communiies. Poor, acidic soils low in organic mater, the nutrients are in the plants. Wet and dry seasons, each are half a year (organisms have adapted to this) Erosion-prone soils (can lead to severe soil loss) Africa, south america, australia, india, other dry tropical regions.
