As we proceed from left to write in this table, we are proceeding into the things that make up the things to the left. Organisms are made of organ systems, organ systems are made of organs, and so on. Now, let's ask whether we can extend this table a bit. Ribosomes are large molecules that make proteins.

However, I cannot resist throwing in one more look at the Meaning of Life in a biological sense.
