Show Answer
Answer:
Correct Answer: A
Solution:
The larval stages of Porifera are motile, which means they can move/swim. Adult sponges, on the other hand, are sessile, meaning they are permanently attached to a surface or substratum and do not move.
Pelagic organisms are the ones that live in the open ocean.
Nekton organisms are the ones that swim in the ocean water.
Plankton organisms are the ones that float over the surface of ocean water.
