Transcript of Terrestrial Biomes

A biome is a large community of plants and animals that occupy a distinct region. Terrestrial biomes are usually characterized by their climate (temperature and rainfall) and the dominant vegetation. Terrestrial biomes include grassland, tundra, tropical rainforest, deciduous forest, and coniferous forest. Terrestrial Biomes of the World A wide variety of plants, dominated by trees.
Provides a variety of habitats for a variety animals. (birds, deer, bears, mice, opossum, insects, etc.) - Deciduous forests: moderate temps., changes a lot during the 4 seasons, abundant precipitation, deciduous trees loose their leaves each fall, nutrient rich soils There are three types Tropical Rainforest Forests Tropical Rainforest: constant hot temperatures, high humidity, daily afternoon rains, poor soils, hardwood trees, most animals live in the canopy, most biologically diverse Deciduous forests: moderate temperatures which vary during the 4 seasons, abundant precipitation, deciduous trees loose their leaves each fall, nutrient rich soils Temperate Deciduous Taiga/Boreal Winters are long & dry, plentiful snowfall & short days, temperatures range from cool to extremely cold, dominated by conifers Precipitation is high enough to allow grass to grow.
Droughts and fires prevent permanent forests.
Home to large herbivores (bison, zebras etc.) and many borrowing animals (meerkats, prairie dogs.) Grasslands Savanna (Tropical Grassland): high average temperatures with a prolonged dry season of 4-6 months. The rest of the year is wet. Savanna Prairie (Temperate Grasslands): Strong winds that blow almost continuously & evaporation is rapid. Prairie Tundra Tundra (Polar Grasslands): Most of the year the climate is extremely cold with high winds & snow cover. Winters are long and average precipitation is low (mostly snow.) Precipitation is low and limited
Evaporation exceeds precipitation
(Rain dries out very fast)
Light vegetation & clear skies
Most animals are small and nocturnal
(come out at night)
Hot days – Cool nights!! Deserts Tropical Desert - hot all year, few plants,
wind-blown surfaces
EX: Sahara Tropical Desert Temperate Deserts - Daytime temperature hot in summer & cool in winter
Ex: The Mojave Desert Temperate Desert Cool Desert – Warm summers & cold, cold winters. It is a rain shadow desert formed by the Himalaya range blocking rain-carrying clouds from the Indian Ocean from reaching the Gobi territory. Cool Desert Brr! It's cold!! The Gobi desert was created by a rain shadow effect from the Himalayan mountains. Thank you for visiting my world!
