1.
The organism shown in the picture above is sessile. That is, it is not free-moving. It also has
many pores, or holes, that allow water to flow into it. Specialized cells within the organism take
in food and oxygen from the water and deposit wastes back into the water. The organism then
pumps the water into a central cavity and out through a hole in its top.

A. phylum Mollusca.
B. phylum Porifera.
