How is water moved through a sponge?
Tiny collar cells with flagella pump the water through the sponge and it is released through the osculum.
200
How do most corals get most of their food?
They live in endosymbiotic relationships with algae that give them food.
200
What kind of symmetry do worms have?
bilateral symetry
200
What do each of these eat? - carnivore - herbivore - omnivore
Carnivores eat meat, herbivores eat plants, and omnivores eat both.
300
Do ANY animals have cell walls?
no

What kind of worms are "very numerous and widely found"?
roundworms
400

They are organisms that live on or near the sea bed.
500
What are the four major groups of cniderians?
They are Anthozoa, Cubozoa, Hydrozoa, and Scyphozoa
500
Why do worms live in moist environments?
They require a moist environment to allow oxygen to diffuse into their cells from water.
