Chapter 1 Section 4 Biomes Contain Many Species
Objectives: 1. Describe how biomes vary by region and how
they are classified by the plant life they support 2. Explain that different ecosystems make up
biomes 3. Describe different land and water biomes
Regions of Earth are Classified into Biomes
A biome is a large geographic area that are similar in climate and have similar organisms
Climate describes long-term weather patterns of a region (Avg. Rainfall & Avg. Temp.)
Climate and abiotic factors are important factors that influence which organisms can live where.
Biomes cover very large areas, so there are many ecosystems within biomes.
Biomes There are six major land biomes and two major
water biomes 1. Taiga 2. Tundra 3. Desert 4. Grassland 5. Temperate Forest 6. Tropical Forest
Water Biomes 1. Freshwater 2. Marine Biomes
TAIGA
Taiga Found in the northern regions of the Earth Characterized by long cold winters and short cool
summers. Temperatures range from -40 to 20 degrees
Celsius Receives 30 – 60 cm of precipitation Evergreen (conifers) tree dominant the
landscapes Primary Consumers: Deer, Elk, Hares, Beavers Predators: Lynx, Owls, Bears, Wolves
TUNDRA
Tundra Found in the northern most and southern most
parts of the Earth. A long cold winter and a short cool summer. Temperatures range from -50 to 18 degrees Celsius Less than 25cm of precipitation per year Permafrost is a deep layer of permanently frozen
soil (below the surface soil) Plants: Moss, Grasses, Shrubs Primary Consumers: Rodents, Caribou, Musk Oxen Predators: Grizzly Bears, White Fox, Owls
DESERT
Desert Found toward the middle latitudes. Receive less than 25cm of precipitation. The organisms here get by on very little
precipitation Producers: Cactus, grass, shrubs Primary Consumers: Kangaroo Rat, Ground
Squirrel Secondary Consumer: Collared Lizard, Scorpion Predators: Snakes, Owls, Foxes
Grasslands
Grassland Receive 50 – 90 cm of rainfall per year Enough for grasses but forests Warm summers (30 degrees Celsius) cold winters Home to some of the largest animals on Earth Primary Consumers: Bison, Wild Horses, Gazelle,
Zebra, Elephant Predators: Wolves, Tigers, Lions, Cheetah
Temperate ForestsDeciduous Forest
Coniferous Forest (Taiga or
Boreal)
Temperate Forest Receive 75 – 150cm of precipitation per year A deciduous forest contains deciduous trees (shed
their leaves) Oak, Maple A coniferous forest contains conifers They support a wide range of animals Primary Consumers: Mice, Chipmunks, Raccoon,
Deer Predators: Bobcats, Foxes, Coyote, Wolves,
Mountain Lions
TROPICAL RAIN FOREST
Tropical Forests Located near the equator where the weather is
warm all year (25 deg. Celsius) It’s the wettest land biome (250 – 400 cm of rain) More organisms live in the tropical rain forests
than anywhere else on Earth Ex. Toucan, Orangutan, Boa Constrictor, Red
Eyed Tree Frog
FRESHWATER BIOME
Freshwater Freshwater biomes are rivers, streams, lakes,
ponds Estuary is where the freshwater of a river meets
the saltwater of an ocean. They are often called marshes or wetlands.
MARINE BIOME
Marine Biomes Marine biomes are saltwater biomes. Three main types: coastal, open ocean, deep
ocean. Beaches are part of the coastal ocean biome. Crabs and clams thrive here. Many types of fish and other marine animals No plants in the open ocean. The deep ocean is very cold and dark. Animals here feed on materials that fall down from
upper levels. Home to many bizarre looking creatures.
Deep Ocean Organisms
Viperfish Dragonfish
Long-Nosed Chimaera Deep Sea Gulper Eel
