Communities, Biomes, And Ecosystems

Biomes

100

This biome is characterized by broad-leaved, deciduous trees, well defined seasons, and average yearly precipitation of 75-150cm  

Temperate Forest

200

hot wet biome year-round humidity; contains Earth's most diverse species of plants and animals

Tropical Rainforest

300

biome characterized by small trees and mixed shrub communities 

Woodland

400

biome south of the tundra with dense evergreen forests and long, cold, dry winters

Boreal Forest

500

Biome characterizedd by deciduous and evergreen trees, a dry season and animal species that include monkeys, elephant and bengal tigers

Tropical Seasonal Forest 

Aquatic Ecosystems

100

water-saturated land area that supports aquatic plants

Wetlands 

200

area of a lake or pond closest to the shore

littoral zone 

300

deepest, coldest area of large lake with little light and limited biodiversity

profundal zone 

400

well-lit, open water area of a lake or pond

Limnetic Zonr

500

unique, transitional ecosystem that supports diverse species and is formed where freshwater and ocean water merge

estuary

Marine Ecosystems

100

open-ocean zone through with sunlight cannot penetrate

aphotic zone 

200

open-ocean zone shallow enough for sunlight to penetrate

photic zone

300

deepest, very cold region of the open ocean

Abyssal Zone

400

ocean-floor area consisting of sand, silt, and dead organisms 

benthic zone 

500

arrow band of shoreline where the ocean and land meet that is alternately submerged and exposed and is home to constantly changing communities 

Intertidal Zone

Types of Succession

100

process by which one community replaces another community because of changing abiotic and biotic factors

Ecological Succession

200

establishment of a community in an area of bare rock or bare sand, where no topsoil is present

Primary Succession

300

change that occurs in a place where soil remains after a community of organisms has been removed

Secondary Succession

400

stable, mature ecological community with little change in the composition of species 

Climax Community 

500

which explains why secondary succession generally occurs more rapidly in an area that does the primary succession

Soil formation has already occured
