Biomes (unit 1) Flashcards
Tropical Rainforest
Around the equator
hot and high prec
low nutrient levels but high productivi
Temperate Rainforest
Mid-latitudes/coastal
warm high precipitation
low nutrient levels (slow decomposition) high productivity
Deciduous Forest (temperate)
Eastern sides of continents
warm moderate precipitation
high nutrient (rapid decomposition) high productivity
Taiga/Boreal Forest
50-60 degrees north
cold moderate precipitation
low nutrient (slow decomp-acidic soils) and low productivity
Desert
30 degrees north and south
hot and dry
nutrient poor lowest productivity
Savanna (tropical)
transition desert to forest
warm- wet summer dry winter
fertile soil (high decomp rate) low/medium productivity
Chaparral/Shrubland
California/coastal argentina
hot dry summer mild rainy winters
low nutrient low production
Temperate grassland/ prairie
mid continents
warm moderate precipitation
fertile soil medium productivity due to fires
Tundra (cold desert)
North of 60 degrees
very cold and dry
nutrient poor and low production
Rivers and Streams
Zero salinity
shallow and cold (floodplain is widest)
rivers have high productivity
Ponds/ FW lakes
Zero Salinity
littoral
near shore
limnetic
near surface
benthic
at bottom
low productivity
oligotrophic
