Final answer:
Bryozoans often live in a group known as a colony. These colonies are made up of individual organisms called zooids, which are filter-feeding invertebrates. They form different types of structures and are commonly found in marine environments.
Step-by-step explanation:
Bryozoans often live in a group, also known as a colony. These colonies consist of individual organisms called zooids, which are filter-feeding invertebrates. The zooids live together and form structures such as gelatinous blobs, branching structures, or encrusting surfaces. Bryozoans are marine immobile organisms that are typically attached to the substrate and feed on suspended particles in the water.
