This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.

So, it is easy for paleontologist to distinguish between a bryozoan and a brachiopod fossil.
The complete Question is:
How could a paleontologist distinguish between a bryozoan fossil and a brachiopod fossil?
A. Bryozoans are large and solitary
B. Zoecia are always found in aggregates
C. You can only distinguish the two by examining the lophophore
D. Bryozoans often look like bivalves
