15/16 aquatic biomes

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
