Animal-like drifting one-celled and small multicellular organisms. Consumers- will eat each other or the phytoplankton.

The Pelagic (water) environment that is beyond the continents' edges. Divided into many zones, from Photic to Abyssal and Hadal.

Top 200 m of ocean; sunlight can penetrate; plankton feeds a food chain.

The zone located above continental shelves. Sunlight, nutrients, moderate temps and pressures.

The most abundant salt in sea water:

We experience 2 high tides and 2 low tides every

A gently sloping, shallow ocean floor at the edge of the continent:

In the Northern Hemisphere, it curves currents to the right:

The ocean zone that runs from the edge of the continental shelf to the deep plains of the ocean at 4-6 thousand meters.

.

The deepest ocean zone; below 6000m, inside ocean trenches.

Ocean zone between the low- and high- tide lines:

free-swimming animals that can move throughout the water column:

tiny, free-floating organisms that occur in aquatic environments:

Which global current is caused from differences in temperature and salinity?

Sunlight does not penetrate this eternal darkness.

Popular sources sometimes refer to this as the midnight

zone. About 5% of the primary production from the

surface makes it to the bottom. Less food means lower

biomass. Occasionally large items like dead sharks or

whales arrive, but generally food is scarce.

made up of a range of mountains that wind through the ocean

The Pelagic (water) environment that is beyond the continents' edges. Divided into many zones, from Photic to Abyssal and Hadal.

How many high (spring) and low (neap) tides a month (every 28 days?)

Which current is caused by winds blowing over the Earth's surface?

The total amount of living tissue within a given trophic level:

Ocean zone on the ocean floor, reaches from the intertidal zone to the Hadal (trench) floors.

Pelagic Zone (Water environment):

the deepest of all the ocean zones

What causes tides to occur?

Spray Zone.

Intertidal zone:

The correct order of ocean zones in the aphotic zone, is:

The area between the high tide and the low tide mark

Organisms that live on or near the bottom

Area from low tide to the gently sloping shallow seabed surrounding a continent.

An organism's marine lifestyle that can swim againist the ocean's currents?

The area between the low tide and the edge of the continental shelf and receives 100% sunlight.

Which ocean zone receives sunlight allowing for plants to go through photosynthesis?

Black dragonfish are monstrous-looking, scaleless fish with very sharp, fang-like teeth. These fish have specialized organs known as photophores that produce light.

Marine mussels are usually found clumping together on wave-washed rocks. When exposed to air they will close their shells and those in the middle of a clump will undergo less water loss.

Phytoplankton are abundant in this ecosystem, because they are buoyant and float in the upper part of the water.

The aphotic zone is

Species living in the Intertidal Zone must be able to survive which changes?

Holes, cracks, or crevices where seawater collects as the tide goes out.

of the intertidal zones it is only exposed during low tide and contains the highest biodiversity.

Of the intertidal zones, it is only submerged at high tide and during low tide is exposed to the sun and atmosphere.

Of the intertidal zones, it is located above high tide, receives constant pounding of the waves, and is exposed to the sun and atmosphere. This intertidal zone has the least amount of biodiversity.

Zone where freshwater and saltwater meet. Made up of lagoons, harbors, inlets, sounds, river or stream mouths and wetlands.

Animals that can use their bodies to make light are called what?

90% of sealife lives in the...

90% of the ocean is in the...

This picture of a fish show what type of marine lifestyle?

Where would we expect to find coral reefs?

Why does most of the ocean life live in or at least visit the ocean surface?

Which statement is true about the abyssopelagic zone?
