16 Terms

1

Littoral zone


around lake, edge shallow, nutrient dense

  • insect larvae, snails, crayfish, birds, turtles, amphibians

New cards
2

limnetic zone

open portion lake or pond far from shore, sunlight penetrates shallow waters

  • light enable photosynthesis, support phytoplankton → zooplankton→ fish

New cards
3

profundal zone


volume of open water sunlight cannot reach

  • no photosynthic life, lower dissolved oxygen than limnetic zone

New cards
4

Benthic zone


along the bottom of lakes an ponds, far from shore to deepest point

  • invertebrates live in mud, feed on detritus

New cards
5

Intertidal zone

band between low/high tide

New cards
6

photic zone

area where sunlight can reach (open ocean)

New cards
7

Aphotic zone

too deep for photosynthesis

New cards
8

acidic soil, spruce/spagnum moss

New cards
9

swamp

New cards
12

salt marsh

estuary habitat, breeding grounds for lots marine life

New cards
13

tributary

small river run into big one

New cards
14

pycnocline

both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth (BOTH SALT/TEMP)

New cards
15

thermocline

the transition layer between warmer mixed water at the ocean's surface and cooler deep water below (TEMP)

New cards
16
