19 The Terrestrial Biomes

20 Tropical Rain Forest cm annual rainfall Warm – found around the Equator High species diversity Soil infertile Many plants are epiphytes AKA jungle Threatened by logging

123 Aquatic Biomes 75% of the earths surface is covered by water Characterized by –Salinity –Temperature –Light levels

124 Freshwater Communities Lakes cover 1.8% of the Earths surface Rivers and streams cover.8% of the earths surface

125 Mountain Stream Swift flowing water Rocks, Mosses Cold

126 Freshwater Lake Still water Distribution of life depends on light and oxygen levels

127 Swamp Flooded forest

128

129 Marsh Wet grassland Natures kidneys

130

131 Marine Communities Shallow waters SurfaceDepths

132 Estuaries Where freshwater and saltwater mingle Bays, lagoons, inlets Organisms found here have to tolerate changes in salinity

140 Beaches and Shores Organisms need to handle tidal extremes and wave action
