Temperate Grassland
Biome characterized by a rich mix of grasses with extremely fertile soils. Summers are warm to hot and moist, winters are cold. Dominant plants are perennial grasses and herbs.
Temperate Forest
Biome contains a mixture of coniferous and deciduous trees. Cold to moderate winters, warm summers, with year round rainfall and fertile soil.
Tropical Dry Forest
BIome has seasonal rainfall and deciduous trees that shed their leaves during the dry season. Generally warm year round and alternating wet and dry seasons. Tall deciduous trees form a canopy in the wet seasosn.
Flowing Water Ecosystem
Rivers, streams, and creeks
Boreal Forest
Sometimes called taiga. Consists of dense evergreen forests of coniferous trees. Winters are bitterly cold, but summers are mild and the ground thaws.
Temperate Woodland or Shrubland
Biome characterized by hot, dry summers and cool, moist winters. Woody evergreen shrubs and fragrant oily hers that grow during the winter and die during the summer. The oil in the low plant herbs contribute to periodic fires
Tropical Savanna
Biome recieves more seasonal rainfall than deserts but less than a tropical dry forest. The main characteristic for this biome is the covering of grasses. Isolated trees and small groves of trees and shrubs with warm temperatures.
Tundra
Characterized by permafrost. During the short sumemr the ground thaws to a depth of a fw centimeters and will freeze again in the winter. The plant life consists of ground hugging plants such as mosses, lichens, sedged, and short grasses.
Tropical Rain Forest
Biome is home to more species than any other biome. The biome is hot and wet year round with thin, nutrient poor soil. Broad leaved evergreen trees, ferns, and vines form a dense canopy covering. A second layer of shorter trees and vines form an understory
bog
Freshwater wetland that forms in depressions where water collects and are dominated by sphagnum moss
Photic zone
IN marine ecosystem the layer that light penetrates
Northwestern Coniferous Forest
Biome has mild, moist area from the Pacific Ocean which provides abundant rainfall. Conifers including giant redwoods, Douglas fir, spruce, and hemlocks are found along with flowering trees and shrubs sometimes call temperate rain forest
Wetland
ecosystem in which water either covers the soil or is present at or near the surface of the soil
Marsh
Freshwater wetland that is shallow and forms along rivers
Estuaries
Wetland formed where freshwater meets salt water
Aphotic zone
In marine ecosystem the layer that is permanently dark
Intertidal zone
Organisms are exposed to regular and extreme changes in their environment. once or twice a day they are submerged in sea water
Desert
Biome defined as having annual precipitation of less than 25 cm. Organismsin this biome can tolerate extreme conditions. soils are rich in minerals but very poor in organic material. DOminant plant life incude cacti and other succulents
Mangrove Swamps
Coastal wetlands of salt tolerant trees called mangroves, seagrases at the low tide line and are nurseries for fish
Open Ocean
Begins at continental shelf and extends outward
swamp
Freshwater wetland that is wet year round
Salt Marsh
temperate zone estuary dominated by solt tolerant grasses above the low tide line and by seagrasses underwater
benthic zone
ocean floor
