100

This ocean zone lies above the continental shelf, extending from the intertidal zone to the edge of the shelf

What is the Neritic Zone?

100

Relationship in which both species benefit

What is mutualism?

100

The color pattern in which marine organisms are light on the bottom and dark on the top of their bodies

What is countershading?

100

This intertidal ecosystem has the lowest species diversity

What is sandy beach?

100

The primary reason the Antarctic marine ecosystem is considered highly susceptible to collapse

What is it relies heavily on a single species (krill) for food web stability?

200

Benthic organisms that are attached to the ocean floor

What is sessile?

200

Organisms that produce their own food

What are Autotrophs?

200

This adaptation helps deep sea organisms attract prey by mimicking small organisms, lighting up the surrounding area, or creating a deceptive lure 

What is bioluminescence?

200

This marine ecosystem plays a vital role in filtering pollutants, serves as a breeding ground for organisms, prevents flooding, and differs from estuaries due to having no freshwater input.

What is a salt marsh?

200

This type of coral reef is characterized by separation from the shoreline by a lagoon and having a steep drop off on the ocean side

What is a Barrier Reef?

300

Organisms that spend most of their time in the water column and can swim freely and faster than currents

What is Nekton?

300

The increasing concentration of toxic substances at each successive trophic level of a food chain

What is biomagnification?

300

The dead/decaying materials and fecal matter from the pelagic photic zone that sinks to the ocean floor

What is marine snow?

300

This marine ecosystem occurs along rocky coastlines, has abundant sunlight, kelp, and is home to fish, otters, urchins, and crabs.

What is a kelp forest?

300

These organisms are the base of the Antarctic food web

What are phytoplankton and algae mats under the ice?

400

Organisms that live in the water column that cannot swim or cannot swim faster than currents

What is Plankton?

400
Competition between different species

What is interspecific competition?

400

These chemosynthetic environments form in the deep sea as a result of salt deposits dissolving into the ocean water

What are brine pools?

400

Deep sea corals, whale falls, and brine pools are all communities of organisms within this marine ecosystem

What is an Abyssal Plain?

400

This type of coral is known for its flexible, tree-like structures that sway with the water currents

What is Branching Coral?

500
The scientific term for drying out

What is desiccation?

500

Most marine organisms are defined as this because they can't regulate their own body temperature and thus have internal temperatures very close to that of their surroundings

What is ectothermic?

500

Compared with animals that have higher internal body temperatures, animals with lower body temperatures tend to

What is move more slowly, consume less food, and reproduce less frequently?

500

This is the defining characteristic of deep sea corals

What is they can live for thousands of years?

500

These organisms are the typical primary consumers in a hydrothermal vent food web

What are tube worms and vent shrimp?
