Ecology Exam 2 Questions And Answers
Latest 2026 Update!!!
terrestrial environment whose biogeochemistry
wetland and vegetation are influenced by the presence
of soils saturated by water
when does saturation occur in wetland throughout the year or only seasonally
what does it mean when plants are emergent they extend above the water line
what happens to plants in a wetland at some
they become emergent
point in the year
why do anoxic conditions develop in saturated O2 infiltration through water is much slower
soils than air
is soil in a wetland oxidized or anoxic anoxic
the depth in soil profile at which soil is saturated
water table
with water
what is water below the depth of the water table
groundwater
called
downhill or along zones of highly porous
how does groundwater flow
material
can cause the water table to intersect with the
uneven slope of land and water table
land surface if the water table is shallow enough
can drive water to the surface at certain
flow through porous layers (water table)
locations along slopes
impermeable clay/frozen ground and water can limit downward flow of water causing it to
table be trapped near the surface
inundation flooding, water table rises above surface
, Fen, Bottomland hardwood forest, cypress
What are 6 types of wetland
swamp, river/stream, coastal tidal marsh
, one major flooding event during spring that
what is flooding like in bottomland hardwood
results in low oxygen in soils during that time
forests
frame
a constant level of water table throughout the
what is flooding like in fens
year. the soil is high oxygen all year round
the water table remains above the surface
throughout the year. the height of the water
what is flooding like in cypress swamps table fluctuated throughout the year, but
remains over the soil. low oxygen content in
soils all year round
fluctuations between the water table being
above the surface and below the surface. high
what is flooding like in river/stream wetland water table levels usually result from
precipitation events. fluctuations occur on a
monthly basis. high peaks in the water table
very frequent fluctuations in the water table
what is flooding like in tidal marshes level. 2 transitions every day known as tides.
oxygen content in soil fluctuates on a daily basis
which type of wetland sees the most transitions
between low and high oxygen in soils over the coastal tidal marshes
course of a year
which type of wetland sees the least transitions
between low and high oxygen in soils over the fens and cypress swamps
course of a year
wet meadow/riparian/flood plain, perched
whata re the 3 classes of wetlands
wetland, coastal tidal wetland
how are wetlands classified by their sources of water
water flows in from around the wetland because
wet meadow/depression/riparian/flood plain
surrounding land is higher in elevation. water is
wetland
exposed to soil before reaching the wetland
source of water is mostly precipitation, not
perched wetland much water interacts with soil before entering
wetland
source of water changes throughout the day.
coastal tidal wetland water either comes from the ocean or as
freshwater from water table
