Classification
100
Cells have higher concentration of dissolved solutes (salt) than their surroundings.
What is hypertonic?
100
This marine life zone is found between the high and low tide. Organisms that live here can tolerate dry and wet conditions.
What is intertidal zone?
100
Plants that are tolerant to salt water.
What are halophytes?
100
A distinct area with distinct abiotic conditions and a community of interacting organisms.
What is an ecosystem?
100
Most inclusive level of taxonomy.
What is kingdom?
200
Cells have a lower concentration of dissolved solutes (salts) than their surroundings.
What is hypotonic?
200
This is the line of seaweed that is deposited on the beach during high tide.
What is the strandline?
200
How deep pelagic organisms get most of their nutrients.
What is marine snow?
200
Organisms that get their energy from the sun.
What are (primary) producers?

Osteichthyes includes fish with this kind of skeleton.
What is bone?
300
Saltwater fish are this to their surroundings.
What is hypotonic?
300
The lake's life zone where rooted, submerged plants can be found.
What is the littoral zone?
300
Typical fish shape that is widest in the middle and tapered in the head and tail regions.
What is fusiform?
300

What are primary consumers?
300
Organisms that swim against the current.
What is nekton?
400
Freshwater fish are this to their surroundings.
What is hypertonic?
400
How a lake's life zones are determined?
What is light penetration?
400
An organ found in bony fish that is used for buoyancy.
What is an air bladder?
400
Organisms that get their energy from primary consumers.
What are secondary consumers?
400
Animals or animal-like organisms that drift in the current.
What is zooplankton?

500
Shark fin used for propulsion.
What is caudal fin?
