coastal environments ecosystems develop along stretches of coast line 2.2
coral reefs
what they need and where they form
temperature
above 18c ideally 22-23c
light
shallow water for sunlight
sediment
clear water
clean
to stop sediment feeding and stop light
wave action
coral like wave action to oxygenate the water
salinity
water needs to be salty
depth
no deeper then 25m for light
in-between topic of cancer and tropic of Capricorn
threat to 'venerable' coral reefs
crown thorns (start fish)
shipping lands
cleared a path though coral
tourist

coastal ecosystems characteristics
biotic
living life with in an ecosystem
e.g.
plants
Abiomass
non - living within an ecosystem
e.g.
rocks
biomass
total of organic matter
e.g.
animals and plants
litter
layer of dead vegetation decomposed into system
salt marshes
where are they found
low anergy zones
high sediment deposition
intertidal zone
brackish water
a mixture of fresh an salty water
all over the world
features
salty and flood tolerant plants
vegation zoning
high biodiversity
channel patterns reuduce wave energy
carbon lock
filters water
