What are areas where freshwater meets saltwater called?
wetlands
coastal byways
intertidal zones
esturaries
What are coral reefs?
rock
deposits of bones of dead fish
outside skeletons of tiny, soft-bodied animals
plants
What special adaptations do intertidal species have?
to resist UV rays
survive heavy waves
survive exposure of air
all the above
Wetlands and esturaries purify water and filter out_______
salt
dead organisms
pollution
waste products
This is the ocean shore between the lowest low tide and the highest high tide.
estuary
shore erosion
intertidal zone
intermoon zone
The distribution of life in aquatic ecosystems is determined by geography, light, depth, temperature, salinity, and dissolved oxygen.

photic zone
aphotic zone
benthic zone
Aquatic ecosystem that recharges the aquifers and filters pollutants.
wetlands
estuaries
mangrove forest
kelp forest
Ecosystem that prevents soil erosion and flooding.

Which ocean ecosytem has extremes in temp, moisture, sun exposure, salinity, predation, and nutrients?
Intertidal Ecosystem
Neritic Ecosystem
Open ocean ecosystem
This ocean ecosystem is at the edge of the continental shelf and contains few nutrients and 90% of the water.
intertidal ecosystem
neritic ecosystem
open-ocean ecosystem
Which part of the open ocean zone has
predators that scavenge carcasses or organic detritus?
photic open ocean zone
aphotic open ocean zone
benthic open ocean zone
Coral reefs require sunlight because reef-building coral contain photosynthetic algae in their tissues. The reefs must sit on the ocean floor for support and must remain underwater to survive. In which ocean zone does a reef most likely thrive?
oceanic
benthic
neritic
intertidal
Based on Jill’s observations, which conclusion could you draw?
Organisms in the intertidal zone must be able to withstand very cold water.
There are no producers in the benthic zone that rely on photosynthesis.
Organisms in the benthic zone must be able to tolerate large amounts of oxygen.
The warm water and abundant sunlight in the nertic zone limits the plankton population.
