Biomes and aquatics
Card Set Information
Biomes and aquatics
what is the nutrients like in lakes and ponds?
seasonal variation, variation by zone
Compare the water depth of lakes and ponds
lake varies but generally deep compared to ponds
light availablility in lakes and ponds?
only in photic zone
What isthe water movement in lake and ponds?
: seasonal turnover
: wind, temperature
What are the different kinds of wetlands?
: shrubs and trees
Describe the nutrients in the wetlands.
low nutrient and low oxgen in bogs and it is acidic
nutrient and oxgyen rich in marshes and swamps
water depth in wetlands?
little standing water in bog; shallow in marsh and swamps
light availibility in wetlands?
N/A for bogs, penetrates to bottom for marshes, pentrates to bottom where canopy is permitted for swamps
what is the water movement like for the wetlands?
bogs are stagnant, no movement; slow moving and unidirectional for marshes; slow moving for swamps
what is the nutrients like in estuaries?
high nutrients, high oxgen
what is the water depth like in estuaries?
generally shallow but varies with flow
light availiability in estuaries, streams and rivers?
penetrates to bottom
what is the water movement of estuaries:
moves in two directions, tidal changes, river/stream flow
what are the nutrient level like in streams and rivers?
depends on flow rate, fast moving: low nutrients, low oxgyen; slow moving: high nutrients, high oxgyen
what is the water depth of streams and rivers?
what is the water movement of streams and rivers?
varies, unidirectional, change in elevation, temperature gradient from start to finish.
nutrient level in oceans
varies depending on zone
water depth and light availability in ocean
deep, only in photic zone
water movement in ocean
depends on location, tidal upwelling, temperature, water currents, air currents
What is the AT and TV for tropical wet forests?
high average temp, very low variation
average precipitation and precipiation variation in wet forests?
very high, high
diveristy in wet forests?
very diverse, exploit many different niches
avg temp high, moderate vartiation
avg p, very low, low variation
acitivity in desert?
30 north and south, a lot of vartaion in acitivty, trigger is precipitation, takes advantage of temporal nature. intense response to rain
: moderate, moderate temp variation
low p, moderate p variation
Can trees be successful in grasslands? why?
too dry for trees to be successful; trees can't be estabished, becuse carbon needs to be stored below graound, trees dont' do that in time of fire
moderate avg temp and temp variation, modeate avg p and low p variation
productivity of temperate forests?
shift of grass to trees of lower productivity than tropical forests
low avg temp, very high temp varation; low avg p and p variation
acitvty of boreal forests? location?
subartic lands south of artic circle; low productivity, slow and steady process of growth, consistent level of acitivity
very low temp, high temp variarion, very low p, low p variation
not covered with ice, trees not in this biome, low line taking advantage of the microclimate as you get lower to the gorund, average very low temperatures
