Form fits function is basically the form of a body part that correlates to the purpose its given.
You are to find 4 different types of planktonic organisms, name the similar body parts they have, then list what it does.
Ex: you have 2 birds (bald eagle and duck). Both the birds have similar looking feet but they each serve a certain purpose. A bald eagles feet are best for hunting. Ducks feet are best for swimming.
Let me know if I need to explain better!
