Name that biome! 2 Flashcards
(30 cards)
Light:
-decreases the deeper it goes
Open ocean
Light:
-grow only in surface waters(lots of light)
Kelp forests and coral reefs
Light:
- highly variable at high tide this is apparent turbidity in sediments
- art low tide there is full light intensity
Intertidal zones
Light:
- highly variable
- full sunlight at low tide
- limited sunlight at high tide due to turbine
Estuaries, salt marshes, and mangrow forests
Light:
-heavenly dependent on: riparian sone, stream with and turbot a
Rivers and streams
Temperature:
-decreases the deeper it goes
Open ocean
Temp:
- help kelp forests restricted to colder waters
- corral reefs restricted to warm water tropics
Kelp forests and coral reefs
Temp:
- dependent on latitude
- varies with air exposure
Intertidal zones
Temp:
-dependent on latitudes even and ocean current
Estuaries, salt marshes, and mangrove forests
Temp:
- varies daily and seasonally
- stratification is rare but can happen in ore pools
- influenced by gorundwater
Rivers and streams
Water movement(WM): -gyres and upwelling due to Coriolanus effect
Open ocean
WM:
-continuously washed by ocean currents (brings oxygen nutrient s and removes waste products)
Kelp forests and corral reefs
WM:
-two main types of tidal systems
- semidurnal tides: two low tides and two high tides per day
- diurnal: 1 low tide and 1 high tide per day
Intertidal zones
WM:
-carries ocean water in during high tide
—carries ocean water out during low tide
Estuaries, salt marshes, and mangrove forests
- considered a logical system: meaning water is moving vs. lentic ecosystems in which water is relatively still such as ponds and lakes
- unidirectional flow-some acceptions with eddies, backwaters and removing some format he florid megssas
- unidirectional flow: such as hitler and stalked because it is strongly inlfluenced strongly influenced by duddent velocity andfemperature
Rivers and streams
Salinity:
- highly variable(influenced by climate: precipitation, evaporation and freshwater coming in
- 34-35 ppt
Open ocean
Salinity:
- kelp forests tolerate salinity
- coral reefs need stable salinity (lethal salinity is 27ppt)
Kelp forests and corral reefs
Salinity:
- can be very high due to evaporation
- can be very low due to heavy rains int he tropics
Intertidal zones
Salinity:
-obviously affects salinity
Estuaries, salt marshes and mangrove forests
Salinity:
- very low: picked up form surrounding soils and surface flow
- exception: some desert streams
Rivers and streams
Oxygen:
- highest near surface
- decreases with depth reaching a min around 100m then increases again to the bottom
- some have anoxic deep water(due to no upwelling)
Open ocean
Oxygen:
-well oxygenated water due to constantly changing incoming ocean currents
Help forests and coral reefs
Oxygen:
- zone can impact the distribution of biota
- exposed to air vs. submerged many adaptions for exposure to atmosphere
- wave action brings in fresh oxygen
Intertidal zones
Oxygen:
- benthic zone is typically anoxic
- usually does not meet the atmosphere due to the tides moving in and out of the surface
- high decomposition rates
- dependent on how photosynthesis occurs
- high turbititiy=low oxygen levels
