This comprehensive guide unlocks the secrets of each biome, revealing the intricate relationships between plants, animals, and their environment.
From the towering forests of the Pacific Northwest to the vast grasslands of the Great Plains, from the sun-drenched deserts of the Southwest to the icy tundra of the Arctic, North America’s biomes offer a breathtaking array of habitats, each with its unique characteristics and ecological significance.
North American Biomes Overview
Biomes are large-scale ecological communities that are characterized by specific climatic conditions and dominant plant and animal species. North America is home to a wide variety of biomes, ranging from temperate forests to deserts to tundras.
The major biomes found in North America include:
- Temperate Deciduous Forest
- Grasslands
- Deserts
- Boreal Forest
- Tundra
- Marine Biomes
Temperate Deciduous Forest
Temperate deciduous forests are characterized by their broadleaf trees, which lose their leaves in the fall. These forests are found in eastern North America, from the Atlantic coast to the Great Plains.
The dominant plant species in temperate deciduous forests include oak, maple, beech, and hickory trees. The dominant animal species include deer, squirrels, raccoons, and foxes.
Temperate deciduous forests are supported by a humid continental climate, with warm summers and cold winters.
Grasslands
Grasslands are characterized by their grasses and few trees. These grasslands are found in central North America, from the Great Plains to the Rocky Mountains.
The different types of grasslands found in North America include:
- Tallgrass prairies
- Mixed-grass prairies
- Shortgrass prairies
The dominant plant species in grasslands include various species of grasses, such as buffalo grass, blue grama, and needlegrass. The dominant animal species include bison, pronghorn antelope, and coyotes.
Grasslands are supported by a semi-arid climate, with hot summers and cold winters.
Deserts
Deserts are characterized by their lack of vegetation and their dry climate. These deserts are found in southwestern North America, from the Sonoran Desert to the Mojave Desert.
The dominant plant species in deserts include cacti, succulents, and creosote bushes. The dominant animal species include lizards, snakes, and scorpions.
Deserts are supported by a dry climate, with hot summers and cold winters.
Boreal Forest, Biomes of north america answer key
Boreal forests are characterized by their coniferous trees, which have needle-like leaves. These forests are found in northern North America, from Alaska to Canada.
The dominant plant species in boreal forests include spruce, fir, and pine trees. The dominant animal species include moose, caribou, and wolves.
Boreal forests are supported by a subarctic climate, with cold summers and long, cold winters.
Tundra
Tundras are characterized by their treeless landscape and their cold climate. These tundras are found in northern North America, from Alaska to Greenland.
The dominant plant species in tundras include mosses, lichens, and sedges. The dominant animal species include reindeer, polar bears, and Arctic foxes.
Tundras are supported by a polar climate, with cold summers and long, cold winters.
Marine Biomes
Marine biomes are characterized by their saltwater environment. These biomes are found off the coast of North America, from the Atlantic Ocean to the Pacific Ocean.
The different types of marine biomes found off the coast of North America include:
- Coral reefs
- Kelp forests
- Seagrass beds
- Open ocean
The dominant plant species in marine biomes include various species of algae and seagrasses. The dominant animal species include fish, marine mammals, and seabirds.
Marine biomes are supported by a variety of factors, including water temperature, salinity, and nutrient availability.
