Final answer:
Bryozoans are filter feeders that use tentacles to trap food. The zooids, which live together as a colony, have a highly variable form and capture microscopic food particles from the water using their tentacles.
Step-by-step explanation:
Bryozoans, a type of aquatic invertebrate, have a unique method to trap food. They are filter feeders that use tentacles to extract food particles from the water. The zooids, which are individual bryozoan organisms, live together as a colony. These colonies have autozooids, which function in feeding the colony and excreting waste. The zooids have a highly variable form, ranging from gelatinous blobs to upright branching structures and sheet-like encrusters. The zooids use their tentacles to capture microscopic food particles from the water.
