Feeding Strategies
Adaptations
Ocean Zones
Plankton
100

These feeders capture nutrients suspended in ocean water

Suspension Feeders

100

Bone and muscle are [more/less] dense than water, while fats and oils are typically [more/less] dense than water

More; Less

100

This zone describes the seafloor

Benthic Zone

100

This term describes microscopic animals

Zooplankton

200

These feeders absorb nutrients from sediment in digestive processes outside the body

Absorptive Feeders

200

This sense allows animals to detect Earth's magnetic field

Magnetoreception

200

This zone includes the entire water mass of the ocean

Pelagic Division

200

These animals are permanently planktonic

Holoplankton

300

These feeders engulf sediments and process them through digestive tracts

Deposit Feeders

300

This form of camouflage is found on marine animals that have light colors on their bellies and dark colors on the top of their bodies

Countershading

300

This zone is the deepest part of the ocean

Hadal Zone

300

These plankton are NOT permanently planktonic

Meroplankton

400

This strategy allows primary producers to obtain energy from inorganic compounds in the absence of sunlight

Chemosynthesis

400

This hypothesis postulates that young salmon traveling downstream are imprinted with a sequence of odors that they can detect later when returning back upstream

Sequential Odor Hypothesis

400

This zone includes water over the continental shelves

Neritic Province

400

Most of these freely swimming pelagic animals start out as meroplankton

Nekton

500

These tube worms lack a digestive tract and rely completely on bacteria in their trophosome to harvest energy for them

Riftia

500

This behavior describes movement of animals to the ocean surface at night then returning to deeper waters during the day

Diurnal Vertical Migration

500

This zone includes many ocean-bottom areas, but is not as deep as the deepest parts of the ocean

Abyssal Zone

500

This Marine Bio teacher is pregnant
