Biology - ch 46 Biomes

Terrestrial biomes - ecosystems

Tundra, Taiga/temperate, rainforest, temperate, edacious forest, tropical, rainforest, shrub, land, temperate grassland, Savannah, desert

Tundra

Has Perma frost

Low growing plants → short growing season

Caribou- migrate in during the summer → leave during the winter

Taiga or temperate rainforest

Montane (mountain)

Coniferous forest is dominant (Olympic nat’l Park)

Temperate deciduous forest

Loose leaves in winter (angiosperms)

Short, harsh winter → longer growing season

Tropical rainforest

Most biologically diverse, understory

Shrubland

Dry Summer - wet winter

Plant species “ like” fire (similar to the high desert)

Temperate grassland

Prairie - Pines and Juniper distributed

Hot summers – cold winter

The Savanna

Varies from grassland to widely space, shrubs, and acacia trees.

support a large amount of animal species

The desert

30%.

Air conditions – hot days – cold nights

Succulents, smaller animals – a little available.

Aquatic ecosystems

Freshwater, salt, water, wetlands, marshland, swamps, Bogs

Freshwater

No salt, streams, lakes, ponds, rivers

Salt water

Ocean

Marshland

Frequently inundated with H2O

Water moves in and out. In between salt and freshwater.

Wetlands

Underwater for a part of the year. In between fresh and saltwater.

Swamps

water areas with woody plants and shrubs

Bogs

What lands with acidic H2O – rain H2O and nutrient poor

Oligotrophic

Nutrient poor – oxygen rich (lakes)

Eutrophic

nutrient rich – oxygen poor (lakes: lots of plants: algae)

Estuary

Salt/freshwater mix – 2/3 marine life depend on this

Mudflaps

Mainly for migratory birds

Mangrove swamps

good for YOUNG to start out their lives

Ocean ecosystem

Takes up 70% of the planet
