Final answer:
The lophophore of a brachiopod has two lobes, consisting of ciliated tentacles for filter feeding, located within the body cavity beneath the brachial valve.
Step-by-step explanation:
The lophophore of a brachiopod is a specialized feeding structure that typically has two main lobes. These lobes consist of ciliated tentacles that are arranged in a horseshoe shape around the mouth, facilitating filter-feeding by the organism. The lophophore is located within the main body cavity or the coelom of brachiopods. As for the positioning, it can be found just below the dorsal valve of the shell, which is also referred to as the brachial valve. This valve often has a characteristic ridge or fold, while the ventral valve, known as the pedicle valve, usually embodies a valley down the middle and possesses a hole, the pedicle opening.
