Biomes can be terrestrial (land) or aquatic (water).Terrestrial Biomes: Terrestrial BiomesTemperate Deciduous Forest: Temperate Deciduous Forest Trees ( birch, oak, maple, elm ) lose leaves in fall Animals such as bears, deer , rabbits, squirrels , & many species of birdsConiferous Forest: Coniferous Forest Cone shaped trees (fir, pine, spruce) Moose , bears, lynxes wolves Snow covered ground during long wintersPowerPoint Presentation: Made up of tall trees with broad leaves that form a dense canopy of vegetation Animals include a wide variety of snakes , lizards , colorful birds , and many kinds of monkeysGrassland: Grassland Made up of grasses & plants that produce colorful flowers Called a prairie in U.S.PowerPoint Presentation: Has rich, fertile soil Well suited for growing crops Animals include bison, mice, and prairie dogsDesert: DesertPowerPoint Presentation: Arid or dry Very little yearly rainfall Vegetation sparse , consists of plants like cacti Animals include snakes, lizards , and jackrabbitsTundra: TundraPowerPoint Presentation: Very cold conditions Very little vegetation Contains permafrost (permanently frozen soil located underneath topsoil Animals include musk oxen & wolvesAquatic Biomes: Aquatic Biomes Aquatic biomes can be freshwater or marinePowerPoint Presentation: Freshwater biomes include rivers, streams, lakes, ponds, and wetlands Wetlands are land areas that remain wet for all or part of the year. They include swamps & marshesPowerPoint Presentation: O ceans have 4 distinct zones: intertidal neritic oceanic benthicPowerPoint Presentation: Intertidal – where ocean meets the land. Animals include shellfish & birds Neritic – numerous fishes, sea turtles, squids, coral reefsPowerPoint Presentation: Oceanic – open ocean; most of zone cold & dark; not much life. Fishes & whales Benthic – ocean floor; bottom feeder animals like starfish, anemones, sponges You do not have the permission to view this presentation.
