Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.

No, sea stars use their tube feet to pry open the clam's shell and then evert their stomach into the clam to digest its soft tissues. Without the use of tube feet, the sea star would not be able to access the clam's flesh to consume it.
Tube feet in echinoderms are adapted for various functions depending on the group. In sea stars, tube feet facilitate locomotion and prey capture by using their adhesive properties to grip surfaces and pull apart shells of prey. In sea urchins, tube feet assist in movement and also play a role in respiration by helping to circulate water over their gills. Meanwhile, in sea cucumbers, tube feet can be modified for feeding, helping to gather food particles from the substrate.
No, tube feet are a characteristic feature of echinoderms, such as sea stars and sea urchins. Protists do not possess tube feet.
One of the functions for tube feet are for movment, and also so they can pry open their clams.
