Feeding Strategies
These feeders capture nutrients suspended in ocean water
Suspension Feeders
Bone and muscle are [more/less] dense than water, while fats and oils are typically [more/less] dense than water
More; Less
This zone describes the seafloor
Benthic Zone
This term describes microscopic animals
Zooplankton
These feeders absorb nutrients from sediment in digestive processes outside the body
Absorptive Feeders
This sense allows animals to detect Earth's magnetic field
Magnetoreception
This zone includes the entire water mass of the ocean
Pelagic Division
These animals are permanently planktonic
Holoplankton
These feeders engulf sediments and process them through digestive tracts
Deposit Feeders
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
This zone is the deepest part of the ocean
Hadal Zone
These plankton are NOT permanently planktonic
Meroplankton
This strategy allows primary producers to obtain energy from inorganic compounds in the absence of sunlight
Chemosynthesis
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
This zone includes water over the continental shelves
Neritic Province
Most of these freely swimming pelagic animals start out as meroplankton
Nekton
These tube worms lack a digestive tract and rely completely on bacteria in their trophosome to harvest energy for them
Riftia
This behavior describes movement of animals to the ocean surface at night then returning to deeper waters during the day
Diurnal Vertical Migration
This zone includes many ocean-bottom areas, but is not as deep as the deepest parts of the ocean
Abyssal Zone
This Marine Bio teacher is pregnant
