Biology section 1-3
Ecosystem
A biological community of interacting organisms and their physical environment.
boreal forest
A forest biome made up primarily of coniferous evergreen trees that can tolerate cold winters and short growing seasons.
Biome
A large ecosystem with a specific climax community
Niche
An organism's particular role in an ecosystem, or how it makes its living.
Perennial
Come back every year
perennial
Comes back every year
coniferous forest
Coniferous trees dominate and below average rainfall
deciduous forest
Deciduous trees dominate.
Grasslands
Grasses and non woody plants are most common. Same as prairies
Grasslands
Grasses and woody plants are common. Same as Prairie
Location of 4 deserts
Great Basin( Nevada) Sonoran (mainly in Arizona into Mexico) Mojave (Southern California and southern Nevada) Chihuahuan (southern New Mexico and western Texas into Mexico.)
The 4 U.S. deserts
Great Basin, Sonoran, Mojave, and Chihuahuan
Population
Group of similar species in a localized area
tall grass aspen parkland
Has aspen trees and is a mixture of grasslands and deciduous forests.
Taiga
Has coniferous forests consisting of pines, spruces, and larches.
Balsam Fir (fir)
Is a coniferous tree. The tree used as a Christmas tree
birch
Is a deciduous tree with peeling bark
Biosphere
Is a global ecosystem composed of living organisms
Permafrost
Is a permanently frozen layer on or under earths surface
prairie
Is dominated by grasses. It has warmer temperatures and is relatively dry.
Community
Is multiple species
Permafrost
Is permanently frozen layer on or under earths surface.
Savanna
Is similar to grasslands . Has a wet and dry climate
aspen
Likes sunlight
Abiotic
Non-living
types of deciduous trees
Oaks, Birch, Maples, cottonwood.
Type of coniferous trees
Pines, Spruce, Fir
Abiotic examples are
Rocks, minerals, water
Ecology
Scientific study of the environment and organisms in it.
bog
Starts from pre-existing lake. Has a cold environment and no soil.
Big Bluestem
Tall grass native to Great Plains
What is boreal forest similar too
The same as taiga.
Hardwood
Wood that comes from deciduous trees
keystone species
a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
Biotic
living things, such as plants, animals, fungi, and bacteria
Tundra
permafrost, cold winters, few to no trees and there is a short growing season.
Minnesota biomes
prairie grassland, deciduous forest, coniferous forest, tallgrass aspen parkland
