Layers of the Ocean
Which layer has the most amount of organisms living in it?
Sunlight
Organisms that eat dead material to break it down into nutrients for soil
How are mollusks divided?
They are divided into classes based on their SHELLS
Is coral considered an animal?
yes!
Corals are animals, because they do not make their own food, as plants do
Name all the layers of the ocean
Sunlight, twilight, dark, abyss & trench
Producer and Consumer
Producer: organisms that make their own food using sunlight
Consumer: organisms that eat food
What are the classes that mollusks are divided into?
Bivalves:have 2-sided shells that open and close like a clam
Univalves: have a single shell that does not open and shut (like a snail)
other mollusks have no shell like a squid or octopus
Describe crustaceans
hard outer shell/skeleton, multiple pairs of legs
Where can bioluminescent organisms live?
Dark (3rd layer of the ocean)
Predator and Pray
Predator: an animal that hunts other animals to eat
they are warm blooded, breathe through lungs, and produce milk for their young.
example: whales
What layer is each found in?
bioluminescent fish
jellyfish
tubeworms
bioluminescent fish - dark zone
jellyfish-sunlit zone
tubeworms- abyss and trenches
Describe the abyss and trench layer
Lowest part of the ocean, water pressure is extreme, temperatures are freezing and very few organisms can live here.
Primary and Secondary Consumer
primary: consumers that eat producers
secondary: consumers that eat other consumers
Name some characteristics for Fish
they are cold blooded, breathe through gills, do NOT produce milk.
example: Sharks
Put the following organisms in order to build a food chain:
crab, killer whale, octopus, plankton
plankton-crab-octopus-killer whale
food chain: diagram that shows the sequence of one organism eating another in a line
food web: a web-like diagram that shows multiple organisms eating and being eaten by multiple organisms
What are the 3 main categories for fish?
DOUBLE POINTS FOR DEFINITIONS
Bony fish- skeletons made of bone
Cartilaginous fish - skeletons made of cartilage
Jawless fish- no jaw
Using your animal kingdom chart, Which PHYLUM contains organisms that sting their prey with tentacles?
