Biomes
Biomes Biosphere- anywhere life is supported – This spans from several miles above the earth surface to deep down in the ocean. If microscopic organisms can live there it is part of the biosphere! Climate-general weather over a long period of time. Climate Includes seasonal changes –
Biomes Biome- Large area of similar climate and life forms. The climate of the are determines the plants which determine the animals –
Terrestrial (Land) Biomes Tundra- cold, dry and treeless area around the northern artic –There is almost no Tundra in the Southern Hemisphere –Permafrost-soil that remains frozen to a depth of 1 meter – 8 -20 inches of precipitation fall each year –Animals-Artic Hare, Artic Fox, Lemmings –Plants-saxifrage/ artic lychnis
Terrestrial Biomes-Forests Coniferous Forest – Has cool temperatures and evergreen conifers –Taiga- where most of the coniferous forests are found –Temperatures from -10 to 57 degrees –Plants-hemlock, spruce, fir –Animals-elk, porcupines, red squirrels
Terrestrial Biomes-Forests Deciduous Foresthas definite seasonal changes, lots of rain and moderate temperatures –Where I live –Long growing season –Animals-white tailed deer, black bear, coyotes –Plants-maple tree, oak tree, elm tree
Terrestrial Biome Tropical Rain Forest- hot and wet area located near the equator. –Approx. 60 inches of rain each year –Divided into 3 layers-ground/trees/canopy –Canopy-the uppermost layer of forest –Animals-sloth, gorilla, spider monkey –Plants-chocolate tree, coconut tree, orchid
Terrestrial Biome Grasslands- needs little rain but has rich soil Animals-bison, praire dog, praire hawk Plants-praire blazing star, sweet cone flower –Praire- North American Grasslands (no trees) –Savanna- grasslands with a few scattered trees
Terrestrial Biome Desert- dry environment with less than 25 cm of rain –Plants- cacti, mesquite bushes –Nocturnal- active mainly at night –Because of the weather conditions, most animals are active at night –Animals-kangaroo rats, gila monster
Aquatic (Water) Biomes Marine- salt water areas • Largest biome on earth • 70% of earth’s surface • Intertidal Zone- covered by water at high tide and not at low tide • Organisms-periwinkles, snails, crab • Neritic Zone- extends from intertidal zone to 200 meters in depth • Organisms- plankton, sea anemone • Oceanic Zone- extends from 200 meter to the bottom of the ocean • Organisms-blue whale, squid
Neritic Zone Oceanic Zone
Aquatic (Water) Biomes Freshwater Biome- lakes, streams and rivers –Animals- carp, dragon flies, frogs –Plants- cattails, reeds Estuaries- where freshwater flows into ocean water. – Very rich with nutrients
