Biomes
Biomes Biome: Large regions of earth that has specific kinds of organisms Rainfall and Temp determine the plant life
Tundra Coldest of all biomes-frozen most of the year There are no trees, very few plants can survive in this environment Little precipitation and short growing seasons
Coniferous forest Forest of conifers (pine trees) Conifers have needles which have a waxy layer to conserve water Average rainfall- 35-75cm Temp- -10C to 14C
Desert Rainfall is less than 25cm/year Soil is sandy and rocky Plants and animals are adapted to low moisture ( Cactus, nocturnal animals
Deciduous Forest Has trees that have leaves Rainfall: 75-125cm These trees lose their leaves to conserve water during the winter Rainfall: 75-125cm Temp: 6C to 28C
Grassland Dominated by grass (not a lot of trees or large shrubs) Rainfall 25-75cm Temp 0C to 25C
Tropical rain forest Very hot and humid Supports a large biodiversity Rainfall 200-450cm Temp 25C to 28C
