1

Match the aquatic biome with the correct salinity/flow.

Draggable itemCorresponding Item
Coral reef
- zero/medium
- zero/fast
Lakes and ponds
- zero/still
Freshwater marsh
- zero to very low/still
Open ocean
- brackish water (~0.5-35 ppt)/still to medium flow
Rivers and streams
- 35 ppt/current and wave action
Estuary
- 35 ppt/current and gyre (variable)
1

Match the aquatic biome with the correct biota (flora/fauna)=(plants/animals).

Draggable itemCorresponding Item
Lakes and ponds
- algae, moss, cattails
- fish (ex: high O2 = trout, low O2= catfish)
Coral reef
- algae, emergent plants (i.e. water lily)
- fish, amphibians, turtle, frogs
Rivers and streams
- grasses, reeds
- dependent; wading birds, elephant, hippo, beaver
Open ocean
- sedges, reeds, mangroves
- fish, crustaceans, wading birds
Freshwater marsh
- algae,
- coral, small fish, larger predatory fish (i.e. snappers)
Estuary
- phytoplankton, kelp, seaweed, seagrass
- large fish, krill, shark, octopus, squid, sea turtle

Match the aquatic biome with the correct abiotic factors.

Draggable itemCorresponding Item
Rivers and streams
- as flows, width increases
- steeper slope = faster = more O2
Estuary
- nutrient runoff causes algal blooms (typically in eutrophic)
Lakes and ponds
- rich in minerals
- soil is saturated most of plant’s growing season
Coral reef
- rich in nutrients
- salt content and water level varies
Open ocean
- typically in shallow water = a lot of sunlight and DO due to waves
- nutrient-poor
Freshwater marsh
- some parts (i.e. tropics) have higher salinity
- upwelling brings up cool, nutrient-rich water
