Biome
A large relatively distinct terrestrial region with similar climate, soil, plants, and animals regardless of where it occurs in the world.
Tundra
The treeless biome in the far north that consists of boggy plains covered by lichens and mosses; it has harsh ,cold winters and extremely short summers.
Boreal forest
A region of coniferous forest (such as pine, spruce, and fir) in the Northern Hemisphere; located just south of the tundra. Also called taiga.
Temperate Rain Forest
a coniferous biome with cool weather, dense fog, and high precipitation.
Temperate Deciduous Forest
A forest biome that occurs in temperate areas where annual precipitation ranges from about 30 to 50in.
Tropical Rain Forest
A lush, species-rich forest biome that occurs where the climate is warm and moist throughout the year.
Chaparral
A biome with mild , moist winters and hot, dry summers; vegetation is typically small-leafed evergreen shrubs and small trees.
Temperate Grassland
A grassland with hot summers, cold winters, and less rainfall that is found in the temperate deciduous forest biome.
Savanna
A tropical grassland with widely scattered trees or clumps of trees.
Desert
A biome in which the lack of precipitation limits plant growth; deserts are found in both temperate and tropical regions.
Standing-water ecosystem
A body of fresh water surrounded by land and whose water does not flow; a lake or pond.
Flowing-water ecosystem
A freshwater ecosystem such as a river or stream in which water flows in a current.
Freshwater wetlands
Lands that shallow fresh water covers for at least part of the year; wetlands have a characteristic soil and water-tolerant vegetation.
Ecosystem services
Important environmental benefits, such as clean air to breath, clean water to drink, and fertile soil in which to grow crops, that the natural environment provides.
Estuary
A coastal body of water, partly surrounded by land, with access to the open ocean and large supply of fresh water from a river.
Evolution
The cumulative genetic changes in populations that occur during successive generations.
Natural Selection
The tendency of better-adapted individuals-those with combination of genetic traits best suited to environmental conditions-to survive and reproduce, increasing their proportion in the population.
Ecological succession
The process of community development over time, which involves species in one stage being replaced by different species.
