Littoral zone
around lake, edge shallow, nutrient dense
insect larvae, snails, crayfish, birds, turtles, amphibians
limnetic zone
open portion lake or pond far from shore, sunlight penetrates shallow waters
light enable photosynthesis, support phytoplankton → zooplankton→ fish
profundal zone
volume of open water sunlight cannot reach
no photosynthic life, lower dissolved oxygen than limnetic zone
Benthic zone
along the bottom of lakes an ponds, far from shore to deepest point
invertebrates live in mud, feed on detritus
Intertidal zone
band between low/high tide
photic zone
area where sunlight can reach (open ocean)
Aphotic zone
too deep for photosynthesis
bog
acidic soil, spruce/spagnum moss
swamp
cyprus trees, uniquely adapted to survivve in submurged soils
marsh
reeds/ cattails
estudiaries
in between fresh/saltwater biome, where river empty to sea
salt marsh
estuary habitat, breeding grounds for lots marine life
tributary
small river run into big one
pycnocline
both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth (BOTH SALT/TEMP)
thermocline
the transition layer between warmer mixed water at the ocean's surface and cooler deep water below (TEMP)
layers of ocean
(EMBAH)
Epipelagic
Mesopelagic
Bathypelagic
Abyssopelagic
Hadalpelagic
